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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400"],"references":["https://github.com/go-git/go-git/security/advisories/GHSA-r9px-m959-cxf4"],"products":["go-git_project:go-git"],"source":"nvd","synced_at":"2026-10-19T21:57:56.913276502+00:00"},"epss":{"cve":"CVE-2025-21614","score":0.00717,"percentile":0.53831,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-r9px-m959-cxf4","url":"https://osv.dev/vulnerability/GHSA-r9px-m959-cxf4","summary":"go-git clients vulnerable to DoS via maliciously crafted Git server replies","modified":"2026-09-10T03:50:22.178489689Z","packages":[{"ecosystem":"Go","name":"gopkg.in/src-d/go-git.v4","purl":"pkg:golang/gopkg.in/src-d/go-git.v4","ranges":[">=4.0.0 <=4.13.1"],"fixed":[]},{"ecosystem":"Go","name":"github.com/go-git/go-git/v5","purl":"pkg:golang/github.com/go-git/go-git/v5","ranges":["<5.13.0"],"fixed":["5.13.0"]},{"ecosystem":"Go","name":"github.com/go-git/go-git","purl":"pkg:golang/github.com/go-git/go-git","ranges":[">=4.0.0 <=4.13.1"],"fixed":[]}]},{"id":"GO-2025-3367","url":"https://osv.dev/vulnerability/GO-2025-3367","summary":"Clients vulnerable to DoS via maliciously crafted Git server replies in github.com/go-git/go-git","modified":"2026-02-04T02:33:58.878534Z","packages":[{"ecosystem":"Go","name":"github.com/go-git/go-git/v4","purl":"pkg:golang/github.com/go-git/go-git/v4","ranges":[">=4.0.0"],"fixed":[]},{"ecosystem":"Go","name":"github.com/go-git/go-git/v5","purl":"pkg:golang/github.com/go-git/go-git/v5","ranges":["<5.13.0"],"fixed":["5.13.0"]},{"ecosystem":"Go","name":"gopkg.in/src-d/go-git.v4","purl":"pkg:golang/gopkg.in/src-d/go-git.v4","ranges":[">=4.0.0"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
