Summary
EnvelopedDatadecryption affectingcryptography< 50.0.0.cryptographyis pulled in transitively (google-authfor the BigQuery example,boto3-related chain for the Athena example) — bumped viauv lock --upgrade-package cryptographyin each example's lockfile, no other packages changed.Note on alert #15
A third open alert (#15) flags
examples/great_expectations/uv.lockfor the same CVE, but that path no longer exists onmain— the directory was renamed toexamples/comparisons/great_expectationsa while back, and its lockfile already pinscryptography50.0.0 (fixed in #48). This looks like a stale/lagging Dependabot alert against an old path rather than a real vulnerability; it should clear on Dependabot's next rescan. No code change needed for it.Test plan
