CVE-2025-53364

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Starting in 5.3.0 and before 7.5.3 and 8.2.2, the Parse Server GraphQL API previously allowed public access to the GraphQL schema without requiring a session token or the master key. While schema introspection reveals only metadata and not actual data, this metadata can still expand the potential attack surface. This vulnerability is fixed in 7.5.3 and 8.2.2.

### Impact The Parse Server GraphQL API previously allowed public access to the GraphQL schema without requiring a session token or the master key. While schema introspection reveals only metadata and not actual data, this metadata can still expand the potential attack surface. ### Patches The issue has been addressed by requiring the master key for schema introspection. Additionally, a new Parse Server configuration option, `graphQLPublicIntrospection`, has been introduced. This option allows developers to re-enable public schema introspection if their application relies on it. However, it is strongly recommended to use this option only temporarily and to update the application to function without depending on public introspection. ### Workarounds None available. ### References - GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-48q3-prgv-gm4w - Fix for Parse Server 7: https://github.com/parse-community/parse-server/pull/9820 - Fix for Parse Server 8: https://github.com/parse-community/parse-server/pull/9819

Parse Server es un backend de código abierto que puede implementarse en cualquier infraestructura que ejecute Node.js. A partir de la versión 5.3.0 y anteriores a las versiones 7.5.3 y 8.2.2, la API GraphQL de Parse Server permitía el acceso público al esquema GraphQL sin necesidad de un token de sesión ni de la clave maestra. Si bien la introspección del esquema solo revela metadatos y no datos reales, estos metadatos pueden ampliar la superficie de ataque potencial. Esta vulnerabilidad se ha corregido en las versiones 7.5.3 y 8.2.2.
