CVE-2026-30863 Details
Description
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.10 and 9.5.0-alpha.11, the Google, Apple, and Facebook authentication adapters use JWT verification to validate identity tokens. When the adapter's audience configuration option is not set (clientId for Google/Apple, appIds for Facebook), JWT verification silently skips audience claim validation. This allows an attacker to use a validly signed JWT issued for a different application to authenticate as any user on the target Parse Server. This issue has been patched in versions 8.6.10 and 9.5.0-alpha.11.
A vulnerability exists in Parse Server authentication adapters for Google, Apple, and Facebook, prior to versions 8.6.10 and 9.5.0-alpha.11. The issue arises because JWT verification, used to validate identity tokens, skips audience claim validation when the audience configuration option is not set. This oversight allows an attacker to use a validly signed JWT from a different application to authenticate as any user on the target Parse Server. The vulnerability is exploitable on unpatched versions if the 'clientId' is not configured for Google or Apple. For Facebook Limited Login, the vulnerability exists regardless of configuration, as the adapter does not pass 'appIds' to JWT verification for audience validation.
Users can upgrade to Parse Server versions 8.6.10 or 9.5.0-alpha.11, where this vulnerability has been patched. For Google and Apple, ensure 'clientId' is set in the adapter configuration. For Facebook Limited Login, there is no workaround other than upgrading.
