SiYuan before 3.8.5 contains an information disclosure vulnerability that allows publish-mode readers to learn backlink block IDs and reference counts from password-protected and publish-disabled documents by querying a published document. Attackers can send POST requests to /api/block/getDocInfo or getDocsInfo for a published document ID to obtain refIDs and refCount of hidden referencing blocks, bypassing the publish confidentiality boundary.
