{"id":"CVE-2025-68144","aliases":["PYSEC-2026-1622"],"url":"https://o3.security/vulnerability/CVE-2025-68144","summary":" mcp-server-git argument injection in git_diff and git_checkout functions allows overwriting local files","details":"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.\n\nThank you to https://hackerone.com/yardenporat for reporting.","published":"2025-12-17T22:50:29Z","modified":"2026-07-07T17:56:33.750487025Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"mcp-server-git","fixedVersion":"2025.12.18"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/modelcontextprotocol/servers/security/advisories/GHSA-9xwc-hfwc-8w59"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68144"},{"type":"PACKAGE","url":"https://github.com/modelcontextprotocol/servers"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-07T17:56:33.750487025Z"}}
