GHSA-qjw6-xvrm-5f2h
HIGHGHSA-qjw6-xvrm-5f2h is a high-severity (CVSS 8.8) Cross-Site Request Forgery (CSRF) vulnerability in io.jenkins.plugins:atlassian-bitbucket-server-integration. O3 Security confirms whether GHSA-qjw6-xvrm-5f2h is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Bitbucket Server Integration Plugin allows bypassing CSRF protection for any URL
Real-World Exposure
io.jenkins.plugins:atlassian-bitbucket-server-integrationReal-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
An extension point in Jenkins allows selectively disabling cross-site request forgery (CSRF) protection for specific URLs. Bitbucket Server Integration Plugin implements this extension point to support OAuth 1.0 authentication.
In Bitbucket Server Integration Plugin 2.1.0 through 4.1.3 (both inclusive) this implementation is too permissive, allowing attackers to craft URLs that would bypass the CSRF protection of any target URL.
Bitbucket Server Integration Plugin 4.1.4 restricts which URLs it disables cross-site request forgery (CSRF) protection for to the URLs that needs it.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.jenkins.plugins:atlassian-bitbucket-server-integration. 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 io.jenkins.plugins:atlassian-bitbucket-server-integration to 4.1.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qjw6-xvrm-5f2h 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-qjw6-xvrm-5f2h 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-qjw6-xvrm-5f2h. 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-qjw6-xvrm-5f2h in your dependencies?
O3 detects GHSA-qjw6-xvrm-5f2h across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
