CVE-2026-73623 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2026-73623, released September 4, 2026. It is not reported as exploited. Patch Radar priority: High.
GitPython before 3.1.54 contains an incomplete denylist in unsafe_git_clone_options that omits --template, allowing attackers to achieve arbitrary command execution during clone operations. Attackers can supply --template pointing to a directory containing malicious post-checkout hooks that execute when git clones the repository.
