GHSA-qjw6-xvrm-5f2h has a CVSS score of 8.8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-qjw6-xvrm-5f2h?

GHSA-qjw6-xvrm-5f2h affects the following packages: io.jenkins.plugins:atlassian-bitbucket-server-integration (Maven). Ecosystems affected: Maven.

How do I fix GHSA-qjw6-xvrm-5f2h?

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.

How do I detect GHSA-qjw6-xvrm-5f2h in my Maven dependencies?

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.

How do I mitigate GHSA-qjw6-xvrm-5f2h if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-qjw6-xvrm-5f2h?

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.

Is GHSA-qjw6-xvrm-5f2h actively exploited in the wild?

No public exploit code has been indexed for GHSA-qjw6-xvrm-5f2h yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-qjw6-xvrm-5f2h?

GHSA-qjw6-xvrm-5f2h has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 20th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-qjw6-xvrm-5f2h?

GHSA-qjw6-xvrm-5f2h is classified as Cross-Site Request Forgery (CSRF) (CWE-352). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-qjw6-xvrm-5f2h published, and has it been updated?

GHSA-qjw6-xvrm-5f2h was published on January 22, 2025 and was last updated on January 22, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-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.
