What it is

SiYuan versions before v3.7.3 contain a metadata disclosure vulnerability in the /api/block/getBlockInfo endpoint that returns document root metadata including title for publish-forbidden documents without publish-access checks. Anonymous readers or publish RoleReader tokens can supply a block ID to retrieve the title, notebook, path, root ID, and icon of documents administrators marked as excluded from publishing.
