{"apiVersion":"1.0","identifier":"CVE-2026-76219","description":"GitPython versions before 3.1.58 contain an arbitrary file overwrite vulnerability in IndexFile.from_tree, IndexFile.reset, and IndexFile.merge_tree methods that append caller-influenced treeish strings to git read-tree without option validation or argument separation. Attackers can inject the --index-output option to overwrite arbitrary files with a valid git-index blob, destroying existing file content at attacker-controlled writable paths.","publishedAt":"2026-08-19T14:17:48","lastModifiedAt":"2026-08-20T16:18:08","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-76219","cvssScore":8.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","epssProbability":0.00277,"riskScore":0.83,"affectedProduct":"GitPython","affectedVersions":"<3.1.58","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-76219","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-76219","en":"https://www.redsauce.net/en/cves/CVE-2026-76219","fr":"https://www.redsauce.net/fr/cves/CVE-2026-76219","pt":"https://www.redsauce.net/pt/cves/CVE-2026-76219","de":"https://www.redsauce.net/de/cves/CVE-2026-76219","sk":"https://www.redsauce.net/sk/cves/CVE-2026-76219","el":"https://www.redsauce.net/el/cves/CVE-2026-76219"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-76219"}}
