Official description

SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the resolveAssetPath endpoint that returns absolute filesystem paths unmodified to CheckAuth-only requests. Attackers can harvest relative asset paths from published documents and submit them to resolveAssetPath to obtain the server's absolute workspace path, disclosing the operating-system username and installation layout.
