Technical details
The vulnerability is an improper input validation flaw (CWE-20) in GitPython's config_writer() method, which passes the section parameter directly to configparser without sanitizing newline characters. While a prior patch (CVE-2026-42215) validated the value parameter, the section and option parameters remain unvalidated. An attacker can inject "\n" sequences into the section argument to write multiple section headers into .git/config; for example, section="user]\n[core" results in both [user] and [core] headers being written. By injecting a malicious [core] section with hooksPath pointing to an attacker-controlled directory, code execution is achieved when any Git hook is triggered. The attack requires local filesystem access and user interaction (triggering a Git hook), but does not require elevated privileges. Patches are available in GitPython 3.1.50 and later.
