Description

The (1) extract_keys_from_pdf and (2) fill_pdf functions in pdf_ext.py in logilab-commons before 0.61.0 allows local users to overwrite arbitrary files and possibly have other unspecified impact via a symlink attack on /tmp/toto.fdf.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for logilab-common, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update logilab-common to 0.61.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rr52-wg7f-8875 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
