CVE-2026-72806: SiYuan: Password (protected) tier omitted in the attribute-view/database publish filter: Reader receives rows of protected documents without the password (publish mode)

September 3, 2026

FilterViewByPublishAccess, the filter renderAttributeView applies for Reader sessions drops rows using only the hidden/forbidden check and never checks the publish password. Its three sibling filters all check both tiers. As a result, a publish RoleReader (or the anonymous account when Publish.Auth.Enable is false) who has not entered a document’s password still receives every database/attribute-view row bound to that password-protected document, the primary cell (title/ID) and all column values.
