CVE-2026-32269

Estado: AnalizadaMedia (6.3)—

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.13 and 8.6.39, the OAuth2 authentication adapter does not correctly validate app IDs when appidField and appIds are configured. During app ID validation, a malformed value is sent to the token introspection endpoint instead of the user's actual access token. Depending on the introspection endpoint's behavior, this could either cause all OAuth2 logins to fail, or allow authentication from disallowed app contexts if the endpoint returns valid-looking data for the malformed request. Deployments using the OAuth2 adapter with appidField and appIds configured are affected. This vulnerability is fixed in 9.6.0-alpha.13 and 8.6.39.

Antes de 9.6.0-alpha.13 y 8.6.39, el adaptador de autenticación OAuth2 no valida correctamente los ID de aplicación cuando appidField y appIds están configurados. Durante la validación del ID de aplicación, se envía un valor malformado al endpoint de introspección de tokens en lugar del token de acceso real del usuario. Dependiendo del comportamiento del endpoint de introspección, esto podría causar que todos los inicios de sesión de OAuth2 fallen, o permitir la autenticación desde contextos de aplicación no permitidos si el endpoint devuelve datos de apariencia válida para la solicitud malformada. Las implementaciones que utilizan el adaptador OAuth2 con appidField y appIds configurados se ven afectadas. Esta vulnerabilidad está corregida en 9.6.0-alpha.13 y 8.6.39."
