{"id":"UBUNTU-CVE-2026-45570","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.","modified":"2026-07-02T18:03:51.434847950Z","published":"2026-05-27T15:16:00Z","upstream":["CVE-2026-45570"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-45570"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-45570"},{"type":"REPORT","url":"https://github.com/go-git/go-git/security/advisories/GHSA-m7cr-m3pv-hgrp"}],"affected":[{"package":{"name":"golang-github-go-git-go-git","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/golang-github-go-git-go-git?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.4.2-3","5.4.2-3ubuntu0.1~esm1","5.4.2-3ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"go-git","binary_version":"5.4.2-3ubuntu0.1~esm2"},{"binary_name":"golang-github-go-git-go-git-dev","binary_version":"5.4.2-3ubuntu0.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45570.json"}},{"package":{"name":"golang-github-go-git-go-git","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/golang-github-go-git-go-git?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.4.2-3build1","5.4.2-4","5.4.2-4ubuntu0.24.04.1","5.4.2-4ubuntu0.24.04.2","5.4.2-4ubuntu0.24.04.2+esm1","5.4.2-4ubuntu0.24.04.3","5.4.2-4ubuntu0.24.04.3+esm1","5.4.2-4ubuntu0.24.04.3+esm2","5.4.2-4ubuntu0.24.04.3+esm3"],"ecosystem_specific":{"binaries":[{"binary_version":"5.4.2-4ubuntu0.24.04.3+esm3","binary_name":"go-git"},{"binary_version":"5.4.2-4ubuntu0.24.04.3+esm3","binary_name":"golang-github-go-git-go-git-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45570.json"}},{"package":{"name":"golang-github-go-git-go-git","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/golang-github-go-git-go-git?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.14.0-1"],"ecosystem_specific":{"binaries":[{"binary_version":"5.14.0-1","binary_name":"go-git"},{"binary_name":"golang-github-go-git-go-git-dev","binary_version":"5.14.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45570.json"}},{"package":{"name":"golang-github-go-git-go-git","ecosystem":"Ubuntu:Pro:26.04:LTS","purl":"pkg:deb/ubuntu/golang-github-go-git-go-git?arch=source&distro=esm-apps%2Fresolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.14.0-1","5.16.2-1","5.16.2-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"go-git","binary_version":"5.16.2-1ubuntu0.1~esm1"},{"binary_version":"5.16.2-1ubuntu0.1~esm1","binary_name":"golang-github-go-git-go-git-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-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"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
