CVE-2026-72803
SiYuan: Missing publish-access filter on getBlockAttrs and batchGetBlockAttrs discloses block attributes (name, alias, memo, custom fields) of protected documents
Impact
SiYuan versions before v3.7.4 fail to enforce publish-access checks in the getBlockAttrs and batchGetBlockAttrs endpoints. Attackers can retrieve block attributes including names, aliases, memos, and custom fields from protected documents by sending POST requests with block IDs.
