Auth bypass in Parse-Community Parse-Server

CVE-2022-31083

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 4.10.11 and 5.2.2, the certificate in the Parse Server Apple Game Center auth adapter not validated. As a result, authentication could potentially be bypassed by making a fake certificate accessible via certain Apple domains and providing the URL to that certificate in an authData object. Versions 4.0.11 and 5.2.2 prevent this by introducing a new `rootCertificateUrl` property to the Parse Server Apple Game Center auth adapter which takes the URL to the root certificate of Apple's Game Center authentication certificate. If no value is set, the `rootCertificateUrl` property defaults to the URL of the current root certificate as of May 27, 2022. Keep in mind that the root certificate can change at any time and that it is the developer's responsibility to keep the root certificate URL up-to-date when using the Parse Server Apple Game Center auth adapter. There are no known workarounds for this issue.
