Impact

Calling an invalid Parse Server Cloud Function name or Cloud Job name crashes server and may allow for code injection.

Patches

Added string sanitation for Cloud Function name and Cloud Job name.

Workarounds

Sanitize the Cloud Function name and Cloud Job name before it reaches Parse Server.
