zfr authentication adapter did not verify validity of tokens
Real-World Exposure
zfr/zfr-oauth2-server-moduleReal-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
Previous to @2ca5bb1c2f11537be8f94ca6867d8d69789e744a (release 0.1.2), tokens weren't checked for validity/expiration.
This potentially caused a security issue if expired tokens were not deleted after the expiration time was past, allowing anyone to still use invalidated authentication credentials.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for zfr/zfr-oauth2-server-module, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update zfr/zfr-oauth2-server-module to 0.1.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rcm4-jv5g-wccm 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-rcm4-jv5g-wccm can be triaged on real exposure rather than presence alone.
Tailored to GHSA-rcm4-jv5g-wccm. 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-rcm4-jv5g-wccm in your dependencies?
O3 Security finds GHSA-rcm4-jv5g-wccm across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
