{"id":"CVE-2026-45570","summary":"go-git: Improper single-quote escaping in go-git SSH transport","details":"go-git is an extensible git implementation library written in pure Go. Prior to 5.19.1 and 6.0.0-alpha.4, go-git's SSH transport constructs the remote exec command by wrapping the repository path in single quotes without escaping single quotes embedded inside the path. A repository path containing a single quote can therefore break out of the quoted region in the exec command and be appended as additional shell tokens. This vulnerability is fixed in 5.19.1 and 6.0.0-alpha.4.","aliases":["GHSA-m7cr-m3pv-hgrp","GO-2026-5496"],"modified":"2026-07-08T07:34:16.931913365Z","published":"2026-05-27T14:59:17.441Z","related":["CGA-4fx8-v7vx-v65m","openSUSE-SU-2026:10831-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-116"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45570.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45570.json"},{"type":"ADVISORY","url":"https://github.com/go-git/go-git/security/advisories/GHSA-m7cr-m3pv-hgrp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45570"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-git/go-git","events":[{"introduced":"0"},{"fixed":"3c3be601aa6c0fd0d536c0d1e4f898b4c60e65fe"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"5.19.1"}],"cpe":"cpe:2.3:a:go-git_project:go-git:*:*:*:*:*:go:*:*","source":"CPE_RANGE"}}],"versions":["v5.19.0","v5.18.0","v5.17.2","v5.17.1","v5.17.0","v5.16.5","v5.16.4","v5.16.3","v5.16.2","v5.16.1","v5.16.0","v5.15.0","v5.14.0","v5.13.2","v5.13.1","v5.13.0","v5.12.0","v5.11.0","v5.10.1","v5.9.0","v5.10.0","v5.8.1","v5.8.0","v5.7.0","v5.6.1","v5.5.2","v5.6.0","v5.5.1","v5.5.0","v5.4.2","v5.4.1","v5.4.0","v5.3.0","v5.2.0","v5.1.0","v5.0.0","v4.13.1","v4.13.0","v4.12.0","v4.11.0","v4.10.0","v4.9.1","v4.7.1","v4.9.0","v4.8.1","v4.8.0","v4.7.0","v4.6.0","v4.5.0","v4.4.1","v4.4.0","v4.3.1","v4.3.0","v4.2.1","v4.2.0","v4.1.1","v4.1.0","v4.0.0","v4.0.0-rc15","v4.0.0-rc14","v4.0.0-rc13","v4.0.0-rc12","v4.0.0-rc11","v4.0.0-rc10","v4.0.0-rc9","v4.0.0-rc8","v4.0.0-rc7","v4.0.0-rc6","v4.0.0-rc5","v4.0.0-rc4","v4.0.0-rc3","v4.0.0-rc2","v4.0.0-rc1","v3.1.1","v3.1.0","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v2.2.0","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45570.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:L"}]}
