A denial of service (DoS) vulnerability was discovered in go-git versions prior to v5.13. 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. Users running versions of go-git from v4 and above are recommended to upgrade to v5.13 in order to mitigate this vulnerability.","published":"2025-01-06T16:20:16.140Z","modified":"2026-08-12T03:51:46.073291741Z","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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:46.073291741Z"}}
