GHSA-gjvc-55fw-v6vq
MEDIUMWallabag user can delete own API client unintentionally
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Blast Radius
wallabag/wallabagReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
Description
wallabag was discovered to contain a Cross-Site Request Forgery (CSRF) which allows attackers to arbitrarily delete API key via /developer/client/delete/{id}
This vulnerability has a CVSSv3.1 score of 6.5.
You should immediately patch your instance to version 2.6.3 or higher if you have more than one user and/or having open registration.
Resolution
This action is now doable only via POST method, which ensures that we can't do it via a 3rd-party website.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for wallabag/wallabag. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update wallabag/wallabag to 2.6.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gjvc-55fw-v6vq is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-gjvc-55fw-v6vq is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-gjvc-55fw-v6vq. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-gjvc-55fw-v6vq in your dependencies?
O3 detects GHSA-gjvc-55fw-v6vq across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
