      "value": "SiYuan is an open-source personal knowledge management system. Prior to 3.7.0, the /api/icon/getDynamicIcon endpoint is explicitly excluded from authentication in SiYuan's kernel router (router.go, \"不需要鉴权\" -- no auth needed). When called with type=8 and a valid block id parameter, this endpoint invokes RenderDynamicIconContentTemplate, which executes a Go template that includes the querySQL and queryBlocks functions. These functions run arbitrary SELECT statements against the SiYuan SQLite database. An unauthenticated network-adjacent attacker who knows a valid block ID can exfiltrate all user note content, tags, asset references, and block attributes from the database. This vulnerability is fixed in 3.7.0."

      "value": "SiYuan es un sistema de gestión de conocimiento personal de código abierto. Antes de la versión 3.7.0, el endpoint /api/icon/getDynamicIcon está explícitamente excluido de la autenticación en el router kernel de SiYuan (router.go, ’?????’ -- no se necesita autenticación). Cuando se llama con type=8 y un parámetro de ID de bloque válido, este endpoint invoca RenderDynamicIconContentTemplate, que ejecuta una plantilla Go que incluye las funciones querySQL y queryBlocks. Estas funciones ejecutan sentencias SELECT arbitrarias contra la base de datos SQLite de SiYuan. Un atacante adyacente a la red no autenticado que conoce un ID de bloque válido puede exfiltrar todo el contenido de las notas de usuario, etiquetas, referencias de activos y atributos de bloque de la base de datos. Esta vulnerabilidad está corregida en la versión 3.7.0."
