Walkthrough

The change validates plugin branch and terminal request parameters, rejects malformed values with HTTP 400, applies path containment checks, and shell-escapes command arguments.

Changes

Input hardening

Layer / File(s)	Summary
Plugin branch validation emhttp/plugins/dynamix.plugin.manager/include/ShowPlugins.php	The plugin manager accepts only valid branch strings and shell-escapes the temporary sed rewrite command.
Terminal parameter validation emhttp/plugins/dynamix/include/OpenTerminal.php	New helpers validate request parameters, identifiers, shells, log paths, and directory paths. Invalid values return HTTP 400.
Terminal command wiring emhttp/plugins/dynamix/include/OpenTerminal.php	Terminal modes use validated parameters, path containment checks, and escaped shell arguments.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to ee999

Malformed terminal and plugin requests are rejected and shell arguments are protected while disk-log output retains its intended behavior; no concrete merge-blocking risk remains.

And guards the terminal everywhere
Paths stay inside their proper line
Shell arguments now stay benign
Bad requests hop away
Safe commands lead the way}

- Line 143: Update the grep command in the disk-log request to pass $dev
directly to escapeshellarg(), preserving the intended regex without embedded
quote characters, and leave /var/log/syslog* unquoted so the shell expands the
glob. Keep the existing wait() flow unchanged.
