What it is

From the CVE record

Parse Server before 8.6.95 and 9.0.0 before 9.10.2-alpha.3 does not resolve file references lacking a URL before passing objects to Cloud Code triggers and LiveQuery, causing an uncaught exception that terminates the process. Attackers able to write to a class with Cloud Code save, find, or delete triggers or LiveQuery enabled, including unauthenticated users when public write access or sign-up is allowed, can crash the server or break subsequent requests.
