Two unrelated broken-access-control fixes from the detail.dev OSS scan, bundled
at the author's request so they land in one review cycle. They share no code —
read them as two PRs in one.

Finding Reachable by
1 Mobile endpoints expand the all-selected sentinel org-wide SELF_SERVICE
2 Sentry tunnel is a full-read SSRF any authenticated user

1 — Mobile select-all expansion (D130)

A SELF_SERVICE user could take custody of every available asset in the
workspace
in a single mobile API call — and the same for kits.

Found by the detail.dev OSS scan (finding D130). Fourth of the select-all
cluster, after #2867 (tags), #2869 (locations) and #2872 (bookings).

The bug

The web list can send an all-selected sentinel instead of ids, meaning
"everything matching the filters I'm looking at". That contract works because
the web client also submits currentSearchParams, so the server rebuilds the
same filtered set.

Mobile has no select-all control and sends no filters — it hardcodes an empty
value:

assetIds: z.array(z.string().min(1)).min(1),   // accepts "all-selected"
…
currentSearchParams: "",                        // nothing to narrow by

So a sentinel reaching a mobile bulk endpoint expanded against an empty
filter
— every matching row in the organization.

Who can reach it: bulk-assign-custody and bulk-release-custody require
asset:custody; the kit intents require kit:custody. SELF_SERVICE holds
both.
So this is a restricted role acting workspace-wide, not an admin doing
something merely unbounded.

bulk-update-location needs asset:update, which restricted roles don't hold —
unbounded, but ADMIN/OWNER only.

Scope: the finding named one endpoint, there were seven sites

Endpoint Sites Reachable by
bulk-assign-custody 1 SELF_SERVICE
bulk-release-custody 1 SELF_SERVICE
bulk-update-location 1 ADMIN / OWNER
kits.bulk-actions 3 (assign / release / update-location) SELF_SERVICE (custody intents)
custody.assign 1 — scalar assetId, wrapped as assetIds: [assetId] SELF_SERVICE

The scalar one is the trap: ["all-selected"] satisfies
includes(ALL_SELECTED_KEY) exactly as a longer list does, so a single-asset
endpoint expands org-wide just as readily as a bulk one. It was found by
parameter.ai on this PR after the first six were fixed — a single-id field
simply does not read as a bulk operation. mobileIdSchema now guards that
shape beside mobileBulkIdsSchema.

I then swept every route funnelling an id into any of the 21 functions that
read ALL_SELECTED_KEY. This was the last one: custody.release and the
-quantity variants call singular services, and the remaining
assetIds: [id] call sites go to createNotes / getBookings, neither
sentinel-aware.

The fix

Reject the sentinel at the schema rather than teaching each service to cope.
A mobile client has no way to produce it legitimately — its presence means a
hand-crafted request.

assetIds: mobileBulkIdsSchema("assetIds"),

One shared helper covers all six sites, so a new mobile bulk endpoint can't
reintroduce this by copying a neighbour.

Why reject rather than support

Making mobile support select-all would mean forwarding real filters from the
client and trusting them — a much larger surface, for a feature the mobile UI
doesn't offer. Refusing is the smaller and more honest change.

Notes from verifying

The kit endpoints already carried comments acknowledging that mobile sends no
filters, and that the resolved set is therefore "every kit in the organization".
The release path had also gained an ownership guard from the earlier
2f20bbd85 fix. So the shape was known — what was missing is that the sentinel
should never have been accepted in the first place, which closes it for the
assign intent too, where no ownership guard applies.

Not a breaking change for the companion app

The obvious risk in rejecting an input is breaking a client that legitimately
sends it. Checked before and after writing the fix:

  • No occurrence of all-selected or ALL_SELECTED anywhere in
    apps/companion/.
  • No select-all control in the companion UI.
  • Its API wrappers (lib/api/custody.ts, lib/api/kits.ts) take explicit
    assetIds: string[] / kitIds: string[] built from scanner selections.

So the sentinel cannot arise from the shipped app — only from a hand-crafted
request, which is exactly what this refuses. No companion release is needed.

Tests

  • app/modules/api/mobile-bulk-ids.server.test.ts (7) — sentinel alone, sentinel
    mixed with real ids, empty list, the message naming its field, and that an id
    merely containing the string is still accepted.
  • mobile.bulk-assign-custody.test.ts (+2) — end-to-end: a crafted select-all
    request is refused and bulkCheckOutAssets is never called.
  • mobile.custody.assign.test.ts (+2) — the same, for the scalar field. Added
    to the existing suite; its two prior tests still pass unchanged.

Both route tests were confirmed to return 200 and reach the write with the
guard removed.

11 existing mobile bulk route tests still pass.


2 — Sentry tunnel SSRF (D071)

/api/sentry-tunnel built its upstream URL from the DSN inside the client's
own envelope
, so the destination host was fully attacker-controlled, and it
returned the upstream response body to the caller. That is a full-read SSRF.

Found by the detail.dev OSS scan (finding D071).

The bug

const dsn = JSON.parse(header).dsn as string;   // from the request body
const url = new URL(dsn);
const sentryUrl = `https://${url.hostname}/api/${projectId}/envelope/`;

const sentryResponse = await fetch(sentryUrl, { method: "POST", … });
return new Response(sentryResponse.body, { status: sentryResponse.status, … });

The hardcoded https:// is not a defense

It only constrains the first hop, and the route set no redirect option, so
fetch follows redirects by default:

  1. Attacker points the DSN at a public host they control.
  2. That host answers with 302 → http://169.254.169.254/latest/meta-data/….
  3. fetch chases it — cross-protocol, into link-local space.
  4. The body comes back through the tunnel to the attacker.

I verified this against real sockets before writing the fix, rather than
taking the report's word for it:

redirect followed to a DIFFERENT host:port : true
status returned to caller                  : 200
BODY returned to caller                    : "INTERNAL-SECRET-CREDENTIALS"
=> full-read SSRF: CONFIRMED

Who can reach it: any authenticated user — the route is behind the session
middleware but has no further gate. See the D053 note at the bottom.

The fix

Stop deriving the destination from input at all.

The server already knows the only Sentry project it may talk to — its own
SENTRY_DSN. So the envelope's DSN is now only compared against that, and
the URL we fetch is built entirely from server-side config:

const target = getConfiguredSentryTarget();          // from SENTRY_DSN
if (!target) return 404;                             // nothing legitimate to proxy to
if (!envelopeDsnMatches(dsn, target)) return 403;    // compared, never interpolated
await fetch(buildSentryEnvelopeUrl(target), { …, redirect: "manual" });

Fails closed throughout: an unparseable DSN yields null, and an unset
SENTRY_DSN refuses to proxy rather than falling back to the envelope's value —
that fallback is the bug.

Why not safeFetch?

The repo already has an SSRF guard (~/utils/ssrf.server, from
GHSA-xgrm-8w6v-mvjg). It is the wrong tool here on both counts:

  • It is GET-only and returns a buffer — shaped for image downloads, not an
    envelope POST.
  • More importantly it blocks private/reserved addresses but still permits any
    globally-routable host
    . That is the right boundary for user-supplied image
    URLs, where arbitrary public hosts are the feature. Here they are not — leaving
    it as an open relay that POSTs attacker bytes from our IP.

One legitimate destination means an allow-list of one beats filtering the
internet. redirect: "manual" then closes the redirect leg as defense in depth.

Comparison is on parsed components, never substrings

Host matching by startsWith/endsWith/includes is bypassable from both
ends, so the check compares URL components. Covered by tests:

Attack Why a naive check fails
evil-o123.ingest.sentry.io ends with ours
o123.ingest.sentry.io.evil.com contains ours
https://o123.ingest.sentry.io@evil.com/ ours is userinfo; the host is evil.com
same host, project 999 a free relay into any other Sentry org

Self-hosted deployments

The destination is now the full origin (scheme + host + port) plus the
base path the instance is mounted under. An earlier revision of this PR stored
hostname and the last path segment only, which was still wrong for a
self-hosted Sentry: https://key@sentry.example.com:8443/sentry/456 would have
forwarded to https://sentry.example.com/api/456/envelope/.

To be precise about what is and isn't a regression — the port was dropped by
the pre-fix code too (it also read hostname), and the prefix was mishandled
differently there (pathname.replace("/", "") strips only the first slash,
so it produced /api/sentry/456/envelope/). Neither version produced the right
URL; this one does. Shelf Cloud is root-mounted on the default port, so this
never surfaced in production.

Caught by CodeRabbit — thanks.

Sweep

Per the house rule that this class travels in packs, I grepped for other
server-side fetch calls with an interpolated host. This was the only one —
the CSV imageUrl path already goes through safeFetch.

Tests

  • app/utils/sentry-tunnel.server.test.ts (22) — DSN parsing and the
    host/project comparison, including every look-alike above.
  • test/routes-tests/api+/sentry-tunnel.test.ts (12) — end-to-end.

The route tests assert on the URL passed to fetch, because that is the
sink. A test that only checked the response status would pass while the request
still went to the attacker's host.

All 8 security assertions were confirmed to fail against the pre-fix route
and pass after — verified by restoring the old file, not by assumption.

Follow-ups (not in this PR)

  • D053 — the tunnel is missing from publicPaths, so anonymous client
    errors are 302'd to /login and lost. That fix is now safe to make; doing it
    before this one would have converted an authenticated SSRF into an
    unauthenticated one.
  • Before D053 lands, consider whether an unauthenticated tunnel wants a body-size
    cap. I deliberately left one out here: Sentry envelopes carrying replays or
    large stack traces can be big, and guessing a limit risks silently dropping
    legitimate error reports — a regression that would be invisible.

Summary by CodeRabbit

  • Bug Fixes

    • Mobile bulk actions now reject empty IDs and select-all sentinel values with clear HTTP 400 validation errors.
    • Malformed mobile requests are handled safely without exposing generic server errors.
    • Sentry tunnel requests are restricted to the configured HTTPS destination, blocking unauthorized or attacker-controlled endpoints.
    • Missing or mismatched Sentry configuration now returns appropriate client errors.
  • Tests

    • Added regression coverage for mobile ID validation and Sentry tunnel security, including malformed inputs, alternate destinations, and redirect prevention.

The web list can send an `all-selected` sentinel instead of ids, meaning
"everything matching the filters I am looking at". That only works because the
web client also submits `currentSearchParams` so the server can rebuild the
same set.

Mobile has no select-all control and sends no filters — it hardcodes an empty
`currentSearchParams`. So a sentinel reaching a mobile bulk endpoint expanded
against an EMPTY filter: every matching row in the organization, unbounded and
invisible to the caller. SELF_SERVICE holds `asset:custody` and `kit:custody`,
so on the custody endpoints a restricted role could take custody of every
available asset in the workspace in one request.

Reject it at the schema instead of teaching the services to cope. A mobile
client has no way to produce the sentinel legitimately; its presence means a
hand-crafted request.

The finding named one endpoint. The same shape was on six schemas across four:
bulk-assign-custody, bulk-release-custody, bulk-update-location, and all three
kit intents. One shared helper covers them, so a new mobile bulk endpoint
cannot reintroduce it by copying a neighbour.

Both new route tests were confirmed to return 200 and reach the write when the
guard is removed.

Walkthrough

Added shared mobile ID schemas and updated mobile routes to reject select-all sentinels and malformed bodies. Hardened the Sentry tunnel by pinning forwarding to the configured DSN and validating envelope DSNs.

Changes

Mobile ID validation

Layer / File(s) Summary
Shared mobile-ID schemas
apps/webapp/app/modules/api/mobile-bulk-ids.server.ts, apps/webapp/app/modules/api/mobile-bulk-ids.server.test.ts
Added bulk and scalar schemas. Tests cover valid IDs, empty values, sentinel values, field-specific errors, and valid sentinel substrings.
Asset bulk route validation

Updated bulk asset routes to safely parse bodies and return uncaptured 400 ShelfError responses for malformed bodies or invalid asset IDs.
Scalar asset route validation
apps/webapp/app/routes/api+/mobile+/custody.assign.ts, apps/webapp/test/routes-tests/api+/mobile.custody.assign.test.ts
Updated scalar asset validation to use mobileIdSchema. Tests reject sentinel and empty asset IDs before custody execution.
Kit bulk route validation
apps/webapp/app/routes/api+/mobile+/kits.bulk-actions.ts
Replaced inline kit-ID validation with the shared schema and explicit 400 error handling.

Sentry tunnel hardening

Layer / File(s) Summary
Configured Sentry target validation
apps/webapp/app/utils/sentry-tunnel.server.ts, apps/webapp/app/utils/sentry-tunnel.server.test.ts
Added strict HTTPS DSN parsing, configured-target lookup, host and project matching, and configured envelope URL construction.
Pinned Sentry forwarding
apps/webapp/app/routes/api+/sentry-tunnel.ts, apps/webapp/test/routes-tests/api+/sentry-tunnel.test.ts
The tunnel returns 404 without configuration, returns 403 for mismatched DSNs, forwards only to the configured target, and disables redirects. Tests cover rejected destinations and forwarding behavior.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 3131f

The PR narrows mobile bulk selection and pins Sentry forwarding to the server-configured destination, but it is not merge-ready yet because malformed keyless or nonnumeric DSNs still need to be rejected and the required checks have not completed. These bounded security and readiness issues should be resolved or explicitly accepted before merge.

Warning

Finding on apps/webapp/app/routes/api+/mobile+/custody.assign.ts:45 — could not attach an inline comment (line is not part of the diff), so reporting it here.

🟠 Mobile custody.assign: single assetId field can carry the ALL_SELECTED_KEY sentinel, assigning custody of every asset in the org

POST /api/mobile/custody/assign validates assetId as any non-empty string (z.string().min(1)), then immediately wraps it: assetIds: [assetId]. When assetId === "all-selected" that becomes ["all-selected"], which is exactly the ALL_SELECTED_KEY sentinel. bulkCheckOutAssets → resolveAssetIdsForBulkOperation detects it via assetIds.includes(ALL_SELECTED_KEY) and, because currentSearchParams is hardcoded to "" (falsy), calls getAssetsWhereInput which returns early at if (!currentSearchParams) { return where; } with only { organizationId } — i.e. every asset in the workspace. A SELF_SERVICE user (who holds asset:custody) can therefore send {"assetId":"all-selected","custodianId":"<their own team-member id>"} and take custody of every available asset in the organization in one request. This is the same bug class the PR is patching in the bulk endpoints but was missed in the single-asset endpoint.

Prompt To Fix With AI
In `custody.assign.ts`, the `assetId` field must be rejected when it equals `ALL_SELECTED_KEY` (`"all-selected"`). Apply one of these fixes:

Option A — add a Zod `.refine` on the field:
```ts
import { ALL_SELECTED_KEY } from "~/utils/list";

const { assetId, custodianId } = z
  .object({
    assetId: z
      .string()
      .min(1)
      .refine((id) => id !== ALL_SELECTED_KEY, {
        message: 'assetId must be an explicit asset id, not the "select all" sentinel.',
      }),
    custodianId: z.string().min(1),
  })
  .parse(body);
```

Option B — import and use the new `mobileBulkIdsSchema` helper (wrapping in an array, then extracting) is awkward here; the refine approach is cleaner for a scalar field.

Also consider adding a similar guard in `custody.release.ts` if it accepts an `assetId` string that flows into a sentinel-aware service.

Severity: high | Confidence: 90% | React with 👍 if useful or 👎 if not

Fixed in 193d3c8a.

The four mobile bulk endpoints parsed their body with `.parse()`, so a
validation failure threw a raw ZodError. `makeShelfError` has no branch for
that, so it fell through to the unknown-error path: a CAPTURED 500 with the
generic "Sorry, something went wrong" message.

Verified empirically -- a raw ZodError through `makeShelfError` yields
`status 500, shouldBeCaptured true`.

That matters most for the select-all rejection this PR adds. A crafted
request is an EXPECTED invalid input, and reporting each one as a server
outage buries the signal in Sentry alongside real faults.

Switch all four to `safeParse` and throw a non-captured 400 ShelfError,
matching the pattern already used by `qr.claim.ts`, `qr.$qrId.ts` and
`exchange.ts`.

The route tests asserted `not.toBe(200)`, which passed on the 500 and so
would never have caught this. Tightened to `toBe(400)`.

Raised by Codex in review.
The bulk endpoints were fixed first; `/api/mobile/custody/assign` was missed
because a single-id field does not read as a bulk operation. It is one:

    assetId: z.string().min(1)     // accepts "all-selected"
    ...
    assetIds: [assetId]            // -> bulkCheckOutAssets

`["all-selected"]` satisfies `includes(ALL_SELECTED_KEY)` exactly as a longer
list does, and mobile hardcodes `currentSearchParams: ""`, so it expanded
against an EMPTY filter -- every available asset in the organization. Reachable
by SELF_SERVICE, which holds `asset:custody`.

Adds `mobileIdSchema` beside `mobileBulkIdsSchema` so the scalar shape has a
guard of its own rather than each endpoint hand-rolling a refine, and converts
the route to safeParse -> 400 to match its bulk siblings.

Swept every route that funnels an id into a sentinel-aware service. This was
the only remaining site: custody.release and the -quantity variants call
singular services, and the non-mobile `assetIds: [id]` sites go to createNotes
or getBookings, none of which read the sentinel.

Reported by parameter.ai on this PR, as an out-of-diff finding.

Confirmed and fixed in 193d3c8a8. Good catch — this is a genuine seventh site, and the reason it was missed is exactly the one you name: a single-id field does not read as a bulk operation.

Verified the chain rather than taking it on faith: assetIds: [assetId] → bulkCheckOutAssets → resolveAssetIdsForBulkOperation, whose check is assetIds.includes(ALL_SELECTED_KEY). A one-element array satisfies that exactly as a longer one does, and currentSearchParams: "" is hardcoded two lines below, so getAssetsWhereInput returns early with only { organizationId }. SELF_SERVICE holds asset:custody, so this was reachable by a restricted role.

I went with a shared helper rather than an inline .refine, so the scalar shape is guarded in the same place as the array one and the next mobile endpoint can't reintroduce it by copying a neighbour:

// ~/modules/api/mobile-bulk-ids.server
export function mobileIdSchema(field: string) { … }   // scalar
export function mobileBulkIdsSchema(field: string) { … }  // array

The route also moves to safeParse → non-captured 400, matching the bulk siblings after an earlier Codex finding on this PR.

On your custody.release.ts suggestion — checked, and it does not need the guard. It calls the singular releaseCustody, not a sentinel-aware service, so there is no expansion path. Same for custody.assign-quantity and custody.release-quantity.

Rather than fix just the reported line, I swept every route that funnels an id into any of the 21 functions that read ALL_SELECTED_KEY. custody.assign was the only remaining one; the other assetIds: [id] call sites in the codebase go to createNotes or getBookings, neither of which reads the sentinel.

Regression coverage added to the existing mobile.custody.assign.test.ts suite, asserting the 400 and that bulkCheckOutAssets is never called — confirmed failing against the pre-fix schema.

The tunnel built its upstream URL from the DSN inside the CLIENT's envelope,
so `url.hostname` was fully attacker-controlled. It set no `redirect` option,
and it returned the upstream response body to the caller -- a full-read SSRF.

The `https://` prefix the route hardcoded is not a defense. An attacker points
the DSN at a public host they control, that host answers with a 302 to
`http://169.254.169.254/latest/meta-data/...`, and fetch chases it. Verified
against real sockets before writing the fix: the redirect was followed to a
different host and the internal body came back to the caller.

Stop deriving the destination from input. The server already knows the only
Sentry project it may talk to -- its own SENTRY_DSN -- so the envelope's DSN is
now only COMPARED against that, and the URL fetched is built entirely from
server-side config. When SENTRY_DSN is unset there is no legitimate
destination, so the route refuses rather than falling back to the envelope.

This is deliberately stricter than `safeFetch` (~/utils/ssrf.server), which
blocks private/reserved addresses but still permits any routable host. That is
right for user-supplied image URLs, where arbitrary public hosts are the
feature. Here they are not: one legitimate destination means an allow-list of
one beats filtering the internet. `redirect: "manual"` closes the redirect leg.

Comparison is on parsed URL components, never substrings -- covered for suffix
(`evil-o123.ingest.sentry.io`), subdomain (`o123.ingest.sentry.io.evil.com`)
and userinfo (`https://o123.ingest.sentry.io@evil.com/`) look-alikes.

Tests assert on the URL passed to fetch, since that is the sink; a status-only
test would pass while still reaching the attacker's host. All 8 security
assertions were confirmed to fail against the pre-fix route.

detail.dev finding D071. This also unblocks D053 (the tunnel is missing from
publicPaths, so anonymous errors are lost): adding it there alone would have
turned an authenticated SSRF into an unauthenticated one.
The parser accepted http: while `buildSentryEnvelopeUrl` pins https:. Not
exploitable as written -- the client DSN is only ever compared, never used to
build a URL -- but the asymmetry is a trap: the next editor to derive the
scheme from the parsed target reintroduces plaintext egress.

No behaviour is lost. The tunnel has always egressed over https, so an http
DSN never actually reached a self-hosted http-only Sentry; such a deployment
now fails closed with the "not configured" 404 instead of a failed fetch.

Raised by the pre-commit security reviewer.

Comment thread apps/webapp/test/routes-tests/api+/mobile.custody.assign.test.ts
The invariant under test is "the sentinel is rejected", not "the string
'all-selected' is rejected". With the literal, renaming the constant would
leave these tests passing while asserting nothing meaningful.

CodeRabbit flagged one line; the same literal appeared at three call sites
across two files. Both now import the constant, matching the sibling route
tests (audits.bulk-actions, audits.start) and the unit test for the schema.

Prose references to the wire value are left as-is -- they document what
actually travels over HTTP.

…y tunnel

`SentryIngestTarget` stored `url.hostname`, which drops the port, and kept only
the last path segment, which drops the base path a self-hosted Sentry is
mounted under. So `https://key@sentry.example.com:8443/sentry/456` forwarded to
`https://sentry.example.com/api/456/envelope/` -- a URL that does not exist on
that deployment.

Store `url.origin` (scheme + host + port) and the path prefix, compare both,
and build `<origin><prefix>/api/<projectId>/envelope/`.

The port loss is pre-existing, not a regression: the old code read `hostname`
too. The prefix handling changed shape but stayed wrong -- it used to produce
`/api/sentry/456/envelope/`, putting the prefix inside the api path. Shelf
Cloud is root-mounted on the default port, so neither ever surfaced there.

Security properties are unchanged. `origin` strips userinfo, so
`https://ours@evil.com/` still yields `https://evil.com` and cannot masquerade
as us, and it normalises host case. Taking the scheme from `origin` is safe
because `parseSentryDsn` is the only way to obtain a target and it refuses
anything but https. Two new negative cases pin this: our host on a different
port, and our host under a base path we do not use.

The key is mandatory per Sentry's DSN spec, so a string without one is not a
DSN and should not become a usable destination. It is still not COMPARED --
it is public, it rotates, and origin/prefix/project id are what decide where
bytes go.

Accepting this required fixing six of the security tests. Their DSNs had no
key, so once the check landed they were rejected for the missing key rather
than the wrong host -- still green, but no longer testing the host comparison
they exist to pin. All now carry a key, verified to parse successfully and be
refused on origin:

  https://pubkey@evil.com/456        parsed: true  origin: https://evil.com
  https://o123.ingest.sentry.io@evil.com/456        origin: https://evil.com

Adds JSDoc to the exported SentryIngestTarget type per the repo convention.

Deliberately NOT enforcing a numeric project id, which the same review
suggested. Sentry's SDK spec calls it a string identifier that is only
"usually an integer", so requiring digits would reject a spec-valid
deployment. It buys nothing either: a client-supplied project id is only ever
compared, never used to build a URL. Pinned by a test so the next reader does
not "fix" it.
