Description

All versions of npm-git-publish are vulnerable to Command Injection. The package fails to sanitize input and passes it directly to an execSync call, which may allow attackers to execute arbitrary code in the system. The publish function is vulnerable through the gitRemoteUrl variable.

Recommendation

No fix is currently available. Consider using an alternative package until a fix is made available.
