All versions of priest-runner are vulnerable to Command Injection. The package fails to sanitize input and passes it directly to a spawn call, which may allow attackers to execute arbitrary code in the system. The PriestController.prototype.createChild function is vulnerable since the spawn parameters come from a POST request body.

Recommendation

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