CVE-2026-73049
SiYuan: The publish filter for database backlinks consults the forbidden list instead of the visibility list, disclosing hidden-tier documents to anonymous readers
Impact
SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the getAttributeViewBacklinks endpoint that consults the forbidden access list instead of the visibility list when filtering backlinks. Anonymous readers can supply a publicly visible database row identifier to discover hidden-tier documents that reference it, receiving the database name, row title, and document path of hidden documents.
