{"id":"CVE-2026-76221","summary":"GitPython before 3.1.58 Config Injection via option-name","details":"GitPython before 3.1.58 contains a config-name injection vulnerability in the option-name validator that allows attackers to forge arbitrary git-config directives by injecting equals signs, hash symbols, and whitespace into option names. Attackers can inject malicious option names like 'sshCommand = touch /tmp/RCE #' to execute arbitrary commands via core.sshCommand or core.hooksPath on the next git operation.","aliases":["GHSA-jm78-9fvv-mhgr","PYSEC-2026-3783"],"modified":"2026-09-17T03:47:30.899375581Z","published":"2026-08-19T14:02:04.795Z","related":["SUSE-SU-2026:4072-1","openSUSE-SU-2026:11566-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/76xxx/CVE-2026-76221.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-74"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/76xxx/CVE-2026-76221.json"},{"type":"ADVISORY","url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-jm78-9fvv-mhgr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-76221"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/gitpython-before-config-injection-via-option-name"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gitpython-developers/gitpython","events":[{"introduced":"0"},{"fixed":"30be45d786e95023e23c616fec5cbabca861b44c"}],"database_specific":{"cpe":"cpe:2.3:a:gitpython_project:gitpython:*:*:*:*:*:python:*:*","extracted_events":[{"introduced":"0"},{"fixed":"3.1.58"}],"source":["AFFECTED_FIELD","CPE_RANGE"]}}],"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/osv-test-cve-osv-conversion/osv-output/CVE-2026-76221.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
