Reader-level SQL execution via raw search statement
Published Aug 3, 2026 · Updated Aug 3, 2026
SQL injection in SiYuan before 3.7.3 allows remote attackers to read or modify cleartext notebook content through searchEmbedBlock. The handler passes the client-supplied stmt value unchanged through SearchEmbedBlockInBox to db.Query on the global read-write siyuan.db handle, without single-statement, read-only, or admin checks. A publish RoleReader token is sufficient, and anonymous access exists when publish authentication is disabled; stacked statements affect all opened cleartext notebooks but exclude encrypted notebooks.
