Vulnerability Description
SiYuan versions up to and including v3.7.2 (fixed in v3.7.4) contain an information disclosure vulnerability in the /api/asset/getFileAnnotation endpoint, which returns .sya PDF-annotation file content without a publish-access check. Because the endpoint is gated only by CheckAuth (unlike the /assets/* route, which enforces publish access and password), an anonymous reader (when publish authentication is disabled) or any publish RoleReader who knows an asset path can read the private PDF annotations (highlights and notes) of publish-forbidden, password-protected, or unpublished documents. The issue is limited to non-encrypted notebooks; encrypted-box annotations are not exposed.
