CVE-2026-28292

Описание

A vulnerability was discovered in the simple-git Node.js library. The issue is caused by improper validation of user-supplied input when constructing Git commands. An attacker able to supply specially crafted repository URLs or arguments could exploit Git’s ext:: protocol handler to execute arbitrary commands on the underlying system. This flaw bypasses earlier mitigations intended to restrict unsafe Git protocols. By injecting configuration options that re-enable the ext:: protocol, an attacker could cause the application to execute arbitrary external commands through the Git client. If a vulnerable application passes untrusted input to simple-git operations such as repository cloning or fetching, a remote attacker could exploit this flaw to execute arbitrary commands on the host system with the privileges of the application process.
