CVE-2025-68144: mcp-server-git argument injection in git_diff and git_checkout functions allows overwriting local files
- Severity: high (CVSS 7.1 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 7.2% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2025-12-17 · updated 2026-06-17
- Weakness: CWE-88
Description
In mcp-server-git versions prior to 2025.12.17, 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 2025.12.17 resolve this issue when it is released.
