GHSA-8pjw-fff6-3mjv
HIGHGHSA-8pjw-fff6-3mjv is a high-severity (CVSS 8.1) Improper Authentication vulnerability in org.jenkins-ci.plugins:oic-auth. O3 Security confirms whether GHSA-8pjw-fff6-3mjv is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Jenkins OpenId Connect Authentication Plugin lacks issuer claim validation
Real-World Exposure
org.jenkins-ci.plugins:oic-authReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
Jenkins OpenId Connect Authentication Plugin 4.354.v321ce67a_1de8 and earlier does not check the iss (Issuer) claim of an ID Token during its authentication flow, a value that identifies the Originating Party (IdP).
This vulnerability may allow attackers to subvert the authentication flow, potentially gaining administrator access to Jenkins.
OpenId Connect Authentication Plugin 4.355.v3a_fb_fca_b_96d4 checks the iss (Issuer) claim of an ID Token during its authentication flow when the Issuer is known.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:oic-auth. 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 org.jenkins-ci.plugins:oic-auth to 4.355.v3a or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8pjw-fff6-3mjv 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-8pjw-fff6-3mjv 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-8pjw-fff6-3mjv. 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-8pjw-fff6-3mjv in your dependencies?
O3 detects GHSA-8pjw-fff6-3mjv across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
