How to Fix GHSA-mhcc-g592-267j

To remediate this vulnerability, upgrade all affected Duplicate Advisory dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/siyuan-note/siyuan/kernel fixed: Latest secure release 
Upgrade github.com/siyuan-note/siyuan/kernel to Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/siyuan-note/siyuan/kernel

How to Check if You Are Affected

To determine whether your application is affected by GHSA-mhcc-g592-267j, inspect your project dependencies for Duplicate Advisory:

inspect dependencies for github.com/siyuan-note/siyuan/kernel

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-862: Missing Authorization, where the product does not perform an authorization check when an actor attempts to access a resource or perform an action. In Duplicate Advisory, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-v7ph-r5r6-4jcj. This link is maintained to preserve external references. ## Original 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an asset path can read the private PDF annotations (highlights and notes) of publish-forbidden, password-protected, or unpublished documents.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.
