+  "details": "### Impact\n\nRemote 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.\n\n### Patches\n\nThe fix restricts property lookups during cloud function name resolution to own properties only, preventing prototype chain traversal from stored function handlers.\n\n### Workarounds\n\nThere is no known workaround.",
