CVE-2026-102828

Name of the Vulnerable Software and Affected Versions simple-git versions 3.15.0 through 4.0.0

Description The default blockUnsafeOperationsPlugin fails to classify trailer.<token>.cmd as an unsafe configuration. This allows an attacker to execute arbitrary shell commands with the operating-system identity and permissions of the Node.js process if the application passes attacker-controlled values through SimpleGitOptions.config or inline -c arguments. The execution occurs when git interpret-trailers processes the configured trailer.

Recommendations Update simple-git to version 4.0.1.
