Summary

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.

Patch / fix

  • npm simple-git 3.36.0
  • n/a simple-git 3.36.0
