parse-server's endpoint `/loginAs` allows `readOnlyMasterKey` to gain full read and write access as any user

Impact The readOnlyMasterKey can call POST /loginAs to obtain a valid session token for any user. This allows a read-only credential to impersonate arbitrary users with full read and write access to their data. Any Parse Server deployment that uses readOnlyMasterKey is affected. Patches The fix...
