Description
### 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.
