CVE-2022-24901Network attack vector

Authentication bypass and service interruption via certificate URL

Published May 4, 2022 · Updated Apr 23, 2025

Improper certificate validation in Parse Server before 4.10.10 and 5.0.0 through 5.2.0 allows remote attackers to bypass authentication. The Apple Game Center authentication adapter accepts an attacker-controlled publicKeyUrl with insufficient host and resource validation, then downloads and trusts the referenced certificate. An unauthenticated request must reach a deployment with the Game Center adapter enabled; repeated certificate fetches can interrupt the server without reported data disclosure or modification.
