Prior to version 5.17.1, go-git’s index decoder for format version 4 fails to validate the path name prefix length before applying it to the previously decoded path name. A maliciously crafted index file can trigger an out-of-bounds slice operation, resulting in a runtime panic during normal index parsing. This issue only affects Git index format version 4. Earlier formats (go-git supports only v2 and v3) are not vulnerable to this issue. This issue has been patched in version 5.17.1.","epss":{"date":"2026-11-02","percentile":0.05031,"score":0.00159},"exploits":[],"kev":null,"metrics":[{"score":2.8,"severity":"low","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L","version":"3.1"},{"score":2.8,"severity":"low","source":"NVD: security-advisories@github.com","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:L","version":"3.1"}],"modifiedAt":1793661440417,"publishedAt":1774964862378,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/go-git/go-git/security/advisories/GHSA-gm2x-2g9h-ccm8"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/go-git/go-git/commit/e9b65df44cb97faeba148b47523a362beaecddf9"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/go-git/go-git/releases/tag/v5.17.1"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/go-git/go-git/commit/e9b65df44cb97faeba148b47523a362beaecddf9"},{"source":"security-advisories@github.com","tags":["Product","Release Notes"],"url":"https://github.com/go-git/go-git/releases/tag/v5.17.1"},{"source":"security-advisories@github.com","tags":["Vendor Advisory"],"url":"https://github.com/go-git/go-git/security/advisories/GHSA-gm2x-2g9h-ccm8"},{"source":"OSV / GitHub Security Advisories","tags":["advisory"],"url":"https://github.com/advisories/GHSA-gm2x-2g9h-ccm8"},{"source":"OSV / GitHub Security Advisories","tags":["osv"],"url":"https://osv.dev/vulnerability/GHSA-gm2x-2g9h-ccm8"}],"remediation":[{"kind":"fix","source":"OSV GHSA-gm2x-2g9h-ccm8","text":"github.com/go-git/go-git/v5 (Go): OSV reports a fixed version 5.17.1.
