AI-suggested

Upgrade to steveukx git-js version 4.0.1 or later, where the issue is fixed by properly classifying trailer.<token>.cmd as unsafe configuration. No other mitigations are indicated by the vendor advisory. Patch status is confirmed fixed in 4.0.1.

Description

A command injection vulnerability exists in the steveukx git-js library (simple-git) versions 3.15.0 through 4.0.0. The default blockUnsafeOperationsPlugin does not treat trailer.<token>.cmd as unsafe, allowing attacker-controlled input via SimpleGitOptions.config or inline -c arguments to execute arbitrary shell commands with the Node.js process's OS permissions. This issue is fixed in version 4.0.1.
