gitoxide – Command Injection via Partial .gitmodules Override in gix-submodule_CVE-2026-40034

{
    "lastseen": "",
    "description": "gix-submodule before 0.82.0 incorrectly validates the update field in .gitmodules, allowing attackers to bypass the CommandForbiddenInModulesConfiguration guard when a submodule has been initialized with only partial configuration in .git/config. An attacker can inject arbitrary shell commands via the update field in .gitmodules that will be executed when Submodule::update() is called on a previously-initialized submodule, enabling remote code execution.",
