CVE-2022-31083Network attack vector

Authentication bypass via unvalidated certificate chain

Published Jun 17, 2022 · Updated Apr 23, 2025

Improper authentication in Parse Server before 4.10.11 and 5.0.0 through 5.2.1 allows remote attackers to bypass Game Center authentication. The Game Center adapter fetched the certificate named by authData and verified the signature without chaining that certificate to an Apple root. Exploitation requires the adapter and an attacker-controlled certificate at an accepted Apple-domain URL, allowing a forged Game Center identity to authenticate.
