Doc Text:
A flaw was found in GitPython where it fails to properly validate submodule names within .gitmodules files. A remote attacker could craft a malicious Git repository containing specially formed submodule names with directory traversal sequences. When GitPython processes these malicious submodule names during repository initialization, it could lead to the creation of attacker-controlled Git repositories at arbitrary locations on the filesystem, potentially impacting system integrity.

Description OSIDB Bzimport 2026-08-19 14:18:50 UTC
GitPython before 3.1.58 fails to validate submodule names from .gitmodules files, allowing attackers to create Git repositories at arbitrary filesystem paths outside the intended clone directory. Attackers can craft malicious repositories with traversal sequences in submodule names that GitPython processes during submodule initialization, creating attacker-controlled Git repositories at escaped filesystem locations.
