Description

AI Translation Available

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.24 and 8.6.47, 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. The fix in versions 9.6.0-alpha.24 and 8.6.47 restricts property lookups during cloud function name resolution to own properties only, preventing prototype chain traversal from stored function handlers. There is no known workaround.
