{"id":"CVE-2026-67326","summary":"GitPython before 3.1.50 Newline Injection via config_writer section","details":"GitPython before 3.1.50 fails to validate newline characters in the section parameter of config_writer(), allowing attackers to inject arbitrary section headers into .git/config. Attackers can inject newlines to create a forged [core] section with hooksPath pointing to attacker-controlled directories, achieving remote code execution when git hooks are triggered.","aliases":["GHSA-mv93-w799-cj2w"],"modified":"2026-08-04T11:51:19.220792635Z","published":"2026-08-01T12:22:18.180Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-20"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67326.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67326.json"},{"type":"ADVISORY","url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-mv93-w799-cj2w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67326"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/gitpython-before-newline-injection-via-config-writer-section"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gitpython-developers/gitpython","events":[{"introduced":"0"},{"fixed":"5a294a6fc7ed5dc0946d4b576257bf926178f269"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"3.1.50"}],"source":"AFFECTED_FIELD"}}],"versions":["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-2026-67326.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
