CVE-2026-40034
gitoxide - Command Injection via Partial .gitmodules Override in gix-submodule
CVSS Score
7.8
EPSS Score
0.0%
EPSS Percentile
5th
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.
