Description

CVE-2026-102826 is a command injection vulnerability in the simple-git library (git-js) prior to version 4.0.0. The vulnerability arises because the default blockUnsafeOperationsPlugin does not fully reject unsafe configuration includes supplied via customArgs to git.clone(), allowing attacker-controlled configuration files to be loaded. This can lead to execution of arbitrary commands with the privileges of the Node.js process running the application. The issue is fixed in version 4.0.0.
