SiYuan versions before v3.7.4 contain an authentication bypass vulnerability in the FilterViewByPublishAccess filter that fails to check publish password protection when rendering attribute views and database rows. Unauthenticated readers can access password-protected document rows including titles, block IDs, and column values by calling renderAttributeView without supplying the required password.
