SiYuan before v3.7.4 contains an access control bypass vulnerability where static-file routes in the server mux bypass publish-access controls enforced on the REST API. Attackers with publish reader tokens or anonymous access in disabled-auth mode can read templates, snippets, and export artifacts by directly accessing static routes that lack the same restrictions as their REST API counterparts.
