CVE-2026-67323: GitPython before 3.1.51 Command Injection via unguarded Git options

• Severity: high (CVSS 8.4 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 1.3% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2026-08-01 · updated 2026-10-23
• Weakness: CWE-77

Description

GitPython before 3.1.51 fails to guard against dangerous Git options passed as keyword arguments in Repo.archive() and git.ls_remote(), allowing command injection via options such as --exec/--upload-pack (leading to arbitrary command execution). Additionally, Repo.iter_commits() and Repo.blame() do not check for leading-dash revision arguments, so a revision like --output=<path> can cause Git to open and truncate an arbitrary file. Exploitation requires an application that passes attacker-controlled arguments to these methods.
