CVE-2026-23495

Estado: AnalizadaMedia (4.3)—

Pimcore's Admin Classic Bundle provides a Backend UI for Pimcore. Prior to 2.2.3 and 1.7.16, the API endpoint for listing Predefined Properties in the Pimcore platform lacks adequate server-side authorization checks. Predefined Properties are configurable metadata definitions (e.g., name, key, type, default value) used across documents, assets, and objects to standardize custom attributes and improve editorial workflows, as documented in Pimcore's official properties guide. Testing confirmed that an authenticated backend user without explicit permissions for property management could successfully call the endpoint and retrieve the complete list of these configurations. The vulnerability is fixed in 2.2.3 and 1.7.16.

Antes de las versiones 2.2.3 y 1.7.16, el endpoint de la API para listar Propiedades Predefinidas en la plataforma Pimcore carece de comprobaciones de autorización adecuadas del lado del servidor. Las Propiedades Predefinidas son definiciones de metadatos configurables (por ejemplo, nombre, clave, tipo, valor predeterminado) utilizadas en documentos, activos y objetos para estandarizar atributos personalizados y mejorar los flujos de trabajo editoriales, como se documenta en la guía oficial de propiedades de Pimcore. Las pruebas confirmaron que un usuario de backend autenticado sin permisos explícitos para la gestión de propiedades podría llamar con éxito al endpoint y recuperar la lista completa de estas configuraciones. La vulnerabilidad está corregida en las versiones 2.2.3 y 1.7.16."
