What is CVE-2026-86192?

SiYuan versions prior to v3.8.2 exhibit a vulnerability that fails to adequately filter private attribute-view cell values through the getAttributeViewKeys endpoint. This oversight allows unauthorized users, specifically publish readers, to access hidden KeyValues payloads linked to documents they should not have access to. As a result, sensitive database contents can be exposed without proper authorization, posing a significant risk to data privacy and security.
