CVE-2026-72800

SiYuan versions before v3.7.4 fail to apply publish-access filtering to the getAttributeViewKeysByID endpoint, allowing authenticated readers to retrieve complete database column schemas including descriptions, select vocabularies, and template expressions. Additionally, getBlockDefIDsByRefText and getBlockRelevantIDs endpoints enumerate workspace-wide block IDs without publish scoping, enabling attackers to discover valid block identifiers across publish boundaries and access content from hidden or password-protected documents.

Summary		(es) Las versiones de SiYuan anteriores a la v3.7.4 no aplican el filtrado de acceso de publicación al endpoint getAttributeViewKeysByID, permitiendo a lectores autenticados recuperar esquemas completos de columnas de la base de datos, incluyendo descripciones, vocabularios de selección y expresiones de plantilla. Además, los endpoints getBlockDefIDsByRefText y getBlockRelevantIDs enumeran IDs de bloques de todo el espacio de trabajo sin alcance de publicación, permitiendo a los atacantes descubrir identificadores de bloques válidos a través de los límites de publicación y acceder a contenido de documentos ocultos o protegidos con contraseña.
