No CVSS score has been assigned to CVE-2025-68144 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-68144?

CVE-2025-68144 affects the following packages: mcp-server-git (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2025-68144?

Update mcp-server-git to 2025.12.18 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-68144 is resolved across your whole dependency graph.

How do I detect CVE-2025-68144 in my PyPI dependencies?

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

How do I mitigate CVE-2025-68144 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-2025-68144?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-68144 can be triaged on real exposure rather than presence alone.

Is CVE-2025-68144 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-68144 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-2025-68144?

CVE-2025-68144 has an EPSS (Exploit Prediction Scoring System) score of 7.2%, placing it in the 94th 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-2025-68144 published, and has it been updated?

CVE-2025-68144 was published on December 17, 2025 and was last updated on July 7, 2026. 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 PyPI packages — download data is not available via public APIs for these ecosystems.

Description

In mcp-server-git versions prior to 2025.12.18, the git_diff and git_checkout functions passed user-controlled arguments directly to git CLI commands without sanitization. Flag-like values (e.g., --output=/path/to/file for git_diff) would be interpreted as command-line options rather than git refs, enabling arbitrary file overwrites. The fix adds validation that rejects arguments starting with - and verifies the argument resolves to a valid git ref via rev_parse before execution. Users are advised to update to 2025.12.18 resolve this issue.
