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.
