Code execution via newline-injected hooksPath configuration
Published May 7, 2026 · Updated May 7, 2026
Code injection in GitPython before 3.1.49 allows local users to execute code through newline-bearing Git configuration values. GitConfigParser.set_value() passes embedded newlines to configparser, and _write() turns them into indented lines that Git accepts as a live [core] stanza setting core.hooksPath. Exploitation requires a consuming application to pass attacker-controlled data to set_value() and then perform a Git operation that invokes hooks.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
