{"id":"UBUNTU-CVE-2026-45571","details":"go-git is an extensible git implementation library written in pure Go. Prior to 5.19.1 and 6.0.0-alpha.4, a path validation issue in go-git could allow crafted repository data to affect files outside the intended checkout target, including the repository's .git directory. These validations were introduced in upstream Git years ago, so the vulnerability arose from go-git drifting from those checks. This vulnerability is fixed in 5.19.1 and 6.0.0-alpha.4.","modified":"2026-10-17T12:54:21.088884576Z","published":"2026-05-27T15:16:00Z","upstream":["CVE-2026-45571"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-45571"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-45571"},{"type":"REPORT","url":"https://github.com/go-git/go-git/security/advisories/GHSA-crhj-59gh-8x96"}],"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_version":"5.4.2-3ubuntu0.1~esm2","binary_name":"go-git"},{"binary_version":"5.4.2-3ubuntu0.1~esm2","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-2026-45571.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_name":"golang-github-go-git-go-git-dev","binary_version":"5.4.2-4ubuntu0.24.04.3+esm3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45571.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_name":"go-git","binary_version":"5.14.0-1"},{"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-2026-45571.json"}},{"package":{"name":"golang-github-go-git-go-git","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/golang-github-go-git-go-git?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.16.2-1","5.19.1-1","5.19.2-1"],"ecosystem_specific":{"binaries":[{"binary_version":"5.19.2-1","binary_name":"go-git"},{"binary_name":"golang-github-go-git-go-git-dev","binary_version":"5.19.2-1"},{"binary_name":"golang-github-go-git-go-git-v5-dev","binary_version":"5.19.2-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45571.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_name":"golang-github-go-git-go-git-dev","binary_version":"5.16.2-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-45571.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L"},{"type":"Ubuntu","score":"medium"}]}
