CVE-2026-72791

Full vulnerability record from the local CVENow database.

Description

SiYuan v3.7.4-alpha.1 (a pre-release; the endpoint does not exist in stable v3.7.3 or earlier) contains an information disclosure vulnerability in the /api/av/getAttributeViewFieldViews endpoint. The route is registered with CheckAuth only and applies no publish-access filtering, so reader-role callers can retrieve the complete database view structure — every view's name, icon, layout type, and per-field Hidden flag — for any database whose avID is supplied, regardless of authorization. The issue was introduced by commit acfc02ee8 and fixed in v3.7.4-alpha.2.

La ruta está registrada solo con CheckAuth y no aplica ningún filtrado de acceso de publicación, por lo que los llamadores con rol de lector pueden recuperar la estructura completa de la vista de la base de datos - el nombre de cada vista, icono, tipo de diseño y el indicador ’Hidden’ por campo - para cualquier base de datos cuyo avID sea proporcionado, independientemente de la autorización. El problema fue introducido por el commit acfc02ee2 y corregido en la v3.7.4."
