What is CVE-2026-6951?
CVE-2026-6951 is a critical command injection vulnerability in org.webjars.npm:simple-git, published on 25 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Versions of the package simple-git before 3.36.0 are vulnerable to Remote Code Execution (RCE) due to an incomplete fix for [CVE-2022-25912](https://security.snyk.io/vuln/SNYK-JS-SIMPLEGIT-3112221) that blocks the -c option but not the equivalent --config form. If untrusted input can reach the options argument passed to simple-git, an attacker may still achieve remote code execution by enabling protocol.ext.allow=always and using an ext:: clone source.
