GHSA-f3f8-vx3w-hp5q
CRITICALcodechecker vulnerable to authentication bypass when using specifically crafted URLs
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
codecheckerReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Summary
Authentication bypass occurs when the API URL ends with Authentication, Configuration or ServerInfo. This bypass allows superuser access to all API endpoints other than Authentication. These endpoints include the ability to add, edit, and remove products, among others.
Details
All endpoints, apart from the /Authentication is affected by the vulnerability.
The vulnerability allows unauthenticated users to access all API functionality.
You can look for the following pattern in the logs to check if the vulnerabilty was exploited:
Note that the url starts with v and contains a valid CodeChecker endpoint, but it ends in Authentication, Configuration or ServerInfo and it was made by an Anonymous user.
Impact
This authentication bypass allows querying, adding, changing, and deleting Products contained on the CodeChecker server, without authentication, by an anonymous user.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for codechecker. 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 codechecker to 6.24.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-f3f8-vx3w-hp5q 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-f3f8-vx3w-hp5q 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-f3f8-vx3w-hp5q. 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-f3f8-vx3w-hp5q in your dependencies?
O3 detects GHSA-f3f8-vx3w-hp5q across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
