Summary
Parse Server's Cloud function dispatch crashes server via prototype chain traversal
Details

Impact

Remote clients can crash the Parse Server process by calling a cloud function endpoint with a crafted function name that traverses the JavaScript prototype chain of a registered cloud function handler, causing a stack overflow.

Patches

The fix restricts property lookups during cloud function name resolution to own properties only, preventing prototype chain traversal from stored function handlers.

Workarounds

There is no known workaround.
