This vulnerability allows an attacker to perform denial of service attacks by providing specially crafted responses from a Git server which triggers resource exhaustion in `go-git` clients. \n\nThis is a `go-git` implementation issue and does not affect the upstream `git` cli.\n\n### Patches\nUsers running versions of `go-git` from `v4` and above are recommended to upgrade to `v5.13` in order to mitigate this vulnerability.\n\n### Workarounds\nIn cases where a bump to the latest version of `go-git` is not possible, we recommend limiting its use to only trust-worthy Git servers.\n\n## Credit\nThanks to Ionut Lalu for responsibly disclosing this vulnerability to us.","published":"2025-01-06T16:20:16.140Z","modified":"2026-10-28T02:30:38.951182482Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"gopkg.in/src-d/go-git.v4","fixedVersion":null},{"ecosystem":"Go","name":"github.com/go-git/go-git/v5","fixedVersion":"5.13.0"},{"ecosystem":"Go","name":"github.com/go-git/go-git","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/21xxx/CVE-2025-21614.json"},{"type":"ADVISORY","url":"https://github.com/go-git/go-git/security/advisories/GHSA-r9px-m959-cxf4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-21614"},{"type":"PACKAGE","url":"https://github.com/go-git/go-git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:38.951182482Z"}}
