Last modified Jun 17, 2026

CVE-2026-6951 is a high-severity vulnerability rated 8.2/10 on the CVSS scale. 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.. EPSS estimates a 1.10% chance of exploitation in the next 30 days.
