How severe is CVE-2024-23899?

CVE-2024-23899 has a CVSS score of 6.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2024-23899?

CVE-2024-23899 affects the following packages: org.jenkins-ci.plugins:git-server (Maven). Ecosystems affected: Maven.

How do I fix CVE-2024-23899?

Update org.jenkins-ci.plugins:git-server to 99.101.v720e86326c09 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-23899 is resolved across your whole dependency graph.

How do I detect CVE-2024-23899 in my Maven dependencies?

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

How do I mitigate CVE-2024-23899 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 CVE-2024-23899?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2024-23899 can be triaged on real exposure rather than presence alone.

Is CVE-2024-23899 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-23899 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-2024-23899?

CVE-2024-23899 has an EPSS (Exploit Prediction Scoring System) score of 1.3%, placing it in the 68th 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-2024-23899 published, and has it been updated?

CVE-2024-23899 was published on January 24, 2024 and was last updated on July 9, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

How urgent is this, really

CVE-2024-23899 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.

Where this sits among everything scored

Of 379,145 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description

Jenkins Git server Plugin uses the args4j library to parse command arguments and options on the Jenkins controller when processing Git commands received via SSH. This command parser has a feature that replaces an @ character followed by a file path in an argument with the file’s contents (expandAtFiles). This feature is enabled by default and Git server Plugin 99.va_0826a_b_cdfa_d and earlier does not disable it.

This allows attackers with Overall/Read permission to read the first two lines of arbitrary files on the Jenkins controller file system using the default character encoding of the Jenkins controller process.

See SECURITY-3314 for further information about the potential impact of being able to read files on the Jenkins controller, as well as the limitations for reading binary files. Note that for this issue, unlike SECURITY-3314, attackers need Overall/Read permission.

Fix Description

Git server Plugin 99.101.v720e86326c09 disables the command parser feature that replaces an @ character followed by a file path in an argument with the file’s contents for CLI commands.

Workaround

Navigate to Manage Jenkins » Security and ensure that the SSHD Port setting in the SSH Server section is set to Disable. This disables access to Git repositories hosted by Jenkins (and the Jenkins CLI) via SSH.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
