Unauthenticated database disclosure via incomplete publish filtering
Published Aug 12, 2026 · Updated Aug 12, 2026
Information disclosure in SiYuan before 3.7.4 allows remote attackers to read restricted database content through publish mode. FilterViewByPublishAccess checks only the first cell for row access, never checks Relation or Rollup contents, and returns rows when that cell is not a block. Exploitation requires publish mode and either disabled publish authentication or a reader role, and it exposes hidden, forbidden, or password-protected database data.
