How severe is CVE-2024-23901?

CVE-2024-23901 has a CVSS score of 5.4/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2024-23901?

CVE-2024-23901 affects the following packages: io.jenkins.plugins:gitlab-branch-source (Maven). Ecosystems affected: Maven.

How do I fix CVE-2024-23901?

Update io.jenkins.plugins:gitlab-branch-source to 688.v5fa or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-23901 is resolved across your whole dependency graph.

How do I detect CVE-2024-23901 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.jenkins.plugins:gitlab-branch-source, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-23901 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.

Is CVE-2024-23901 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-23901 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 CVE-2024-23901?

CVE-2024-23901 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 40th 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.

When was CVE-2024-23901 published, and has it been updated?

CVE-2024-23901 was published on January 24, 2024 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.

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

GitLab allows sharing a project with another group.

Jenkins GitLab Branch Source Plugin 684.vea_fa_7c1e2fe3 and earlier unconditionally discovers projects that are shared with the configured owner group.

This allows attackers to configure and share a project, resulting in a crafted Pipeline being built by Jenkins after the next scan of the group’s projects.

In GitLab Branch Source Plugin 688.v5fa_356ee8520, the default strategy for discovering projects does not discover projects shared with the configured owner group. To discover projects shared with the configured owner group, use the new trait "Discover shared projects".
