CVE-2026-102826

What it is

simple-git, an interface for running git commands in any node.js application, enables applications to execute Git operations from JavaScript. Prior to 4.0.0, the default blockUnsafeOperationsPlugin does not completely reject configuration includes supplied through customArgs to git.clone(). The missing include.path classification permits Git to load an attacker-controlled configuration file, and the initial remediation does not cover includeIf.<condition>.path, allowing the same file-loading primitive through a conditional include. A loaded configuration can set an executable Git option such as core.sshCommand, which Git invokes during the clone operation with the privileges of the Node.js process. Exploitation requires the application to pass attacker-influenced custom arguments and requires an attacker-controlled file that the process can read. This issue is fixed in 4.0.0.
