{"id":"CVE-2026-78678","summary":"GitPython before 3.1.59 Arbitrary File Read via Repo.blame()","details":"GitPython versions before 3.1.59 contain an incomplete denylist in the unsafe_git_revision_options guard that omits --contents and -S options, allowing attackers to read arbitrary files by passing these options to Repo.blame(). Attackers can supply revision values like --contents=/etc/passwd to leak file contents through the blame result returned to the caller.","aliases":["GHSA-5xxx-qhh7-9287"],"modified":"2026-08-27T11:47:50.581465120Z","published":"2026-08-25T01:30:35.582Z","related":["openSUSE-SU-2026:11615-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/78xxx/CVE-2026-78678.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-88"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/78xxx/CVE-2026-78678.json"},{"type":"ADVISORY","url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-5xxx-qhh7-9287"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-78678"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/gitpython-before-arbitrary-file-read-via-repo-blame"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/gitpython-developers/gitpython","events":[{"introduced":"0"},{"fixed":"66340d77aab9a7468f4aed3681d4ef1e3c0ec931"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"0"},{"fixed":"3.1.59"}]}}],"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-2026-78678.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:N/VA:N/SC:N/SI:N/SA:N"}]}
