Which packages are affected by GHSA-w2mh-6xj5-f77f?

GHSA-w2mh-6xj5-f77f affects the following packages: org.jenkins-ci.plugins:cloudbees-bitbucket-branch-source (Maven), org.jenkins-ci.plugins:cloudbees-bitbucket-branch-source (Maven), org.jenkins-ci.plugins:cloudbees-bitbucket-branch-source (Maven), org.jenkins-ci.plugins:cloudbees-bitbucket-branch-source (Maven). Ecosystems affected: Maven.

How do I fix GHSA-w2mh-6xj5-f77f?

Update org.jenkins-ci.plugins:cloudbees-bitbucket-branch-source to 746.v350d2781c184 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-w2mh-6xj5-f77f is resolved across your whole dependency graph.

How do I detect GHSA-w2mh-6xj5-f77f in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:cloudbees-bitbucket-branch-source. 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-w2mh-6xj5-f77f 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-w2mh-6xj5-f77f?

O3 pinpoints whether GHSA-w2mh-6xj5-f77f 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-w2mh-6xj5-f77f actively exploited in the wild?

No public exploit code has been indexed for GHSA-w2mh-6xj5-f77f 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-w2mh-6xj5-f77f?

GHSA-w2mh-6xj5-f77f has an EPSS (Exploit Prediction Scoring System) score of 0.9%, placing it in the 53th 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-w2mh-6xj5-f77f?

GHSA-w2mh-6xj5-f77f is classified as CWE-862 (CWE-862). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-w2mh-6xj5-f77f published, and has it been updated?

GHSA-w2mh-6xj5-f77f was published on January 13, 2022 and was last updated on February 16, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Jenkins Bitbucket Branch Source Plugin prior to 746.v350d2781c184, 725.vd9f8be0fa250, 2.9.11.2, and 2.9.7.2 does not perform permission checks in several HTTP endpoints.

This allows attackers with Overall/Read access to enumerate credentials IDs of credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using another vulnerability.
