What is CVE-2026-82652?

The SiYuan application, prior to version 3.8.1, has a critical issue where it does not adequately filter invisible-tier content within SQL embed blocks, attribute-view keys, and attribute-view backlinks during publish mode. This flaw allows anonymous users to enumerate and access unlisted content, despite admin settings intended to restrict visibility. This situation raises significant concerns regarding the confidentiality of information published in the workspace.
