How to fix?

There is no fixed version for Debian:13 rust-gix-submodule.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rust-gix-submodule package and not the rust-gix-submodule package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

gix-submodule before 0.29.0 (gitoxide before 0.5.21, gix before 0.84.0) 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.
