{"id":"CVE-2026-110857","summary":"GitPython before 3.2.0 Command Execution via ls_remote ext:: URLs","details":"GitPython before 3.2.0 contains a remote code execution vulnerability that allows attackers to run commands because Git.ls_remote forwards URLs without check_unsafe_protocols validation. Attackers can supply ext:: remote-helper URLs to execute commands when git permits the ext transport, while merge_base and IndexFile.move also accept unguarded option injection.","aliases":["GHSA-w8jc-g24h-crhw"],"modified":"2026-10-15T10:47:31.161050979Z","published":"2026-10-14T22:52:40.373Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110857.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-1287"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110857.json"},{"type":"ADVISORY","url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-w8jc-g24h-crhw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110857"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/gitpython-before-3.2.0-command-execution-via-ls-remote-ext-urls"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gitpython-developers/gitpython","events":[{"introduced":"0"},{"fixed":"6a7180a9dfcb276755a8af99dd78155f775a6b14"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.2.0"}],"source":"AFFECTED_FIELD"}}],"versions":["3.1.57","3.1.56","3.1.55","3.1.54","3.1.53","3.1.52","3.1.51","3.1.50","3.1.49","3.1.48","3.1.47","3.1.44","3.1.43","3.1.42","3.1.41","3.1.40","3.1.38","3.1.35","3.1.34","3.1.33","3.1.32","3.1.31","3.1.30","3.1.29","3.1.28","3.1.27","3.1.26","3.1.25","3.1.24","3.1.23","3.1.22","3.1.20","3.1.19","3.1.18","3.1.17","3.1.16","3.1.13","3.1.12","3.1.11","3.1.10","3.1.9","3.1.8","3.1.7","3.1.6","3.1.5","3.1.4","3.1.3","3.1.2","3.1.1","3.1.0","3.0.9","3.0.8","3.0.7","3.0.6","3.0.5","3.0.4","3.0.3","3.0.2","3.0.1","2.1.13","3.0.0","2.1.12","2.1.11","2.1.10","2.1.9","2.1.8","2.1.6","2.1.5","2.1.4","2.1.3","2.1.2","2.1.1","2.1.0","2.0.9","winerr_show","2.0.8","2.0.7","2.0.6","2.0.5","2.0.4","2.0.3","2.0.2","2.0.1","2.0.0","0.3.2.1","1.0.2","0.3.7","1.0.1","1.0.0","0.3.6","0.3.5","0.3.4","0.3.3","0.3.2","0.3.2-RC1","0.3.1-beta2","0.3.1-beta1","0.3.0-beta2","0.3.0-beta1","0.2.0-beta1","0.1.6","0.1.5","0.1.4","0.1.4-pre"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110857.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
