Answer in brief
CVE-2026-40034 records a High severity (CVSS 7.3) vulnerability in gitoxide - Command Injection via Partial .gitmodules Override in gix-submodule. The current sources do not mark it as known exploited. The current feed maps gitoxide/gitoxide (generic), gitoxide/gix (generic), gitoxide/gix-submodule (generic), gix (rust). Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.3. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
