    CVE-2026-87817

    Published: 9 Sept 2026Last Modified: 12 Sept 2026

    Summary: GitPython before 3.1.60 Remote Code Execution via Git Directory Impersonation

    Details: GitPython before 3.1.60 fails to properly validate the git directory location, allowing attackers to impersonate the git directory using tracked files like gitdir, commondir, and HEAD. Attackers can execute arbitrary code by placing a malicious pre-commit hook in the tracked hooks directory that executes when a victim calls index.commit() on a cloned or opened repository.
