## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-p4qw-vx5p-g984. This link is maintained to preserve external references.

## Original Description
SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the getAttributeViewBacklinks endpoint that consults the forbidden access list instead of the visibility list when filtering backlinks. Anonymous readers can supply a publicly visible database row identifier to discover hidden-tier documents that reference it, receiving the database name, row title, and document path of hidden documents.

## Affected packages

- `github.com/siyuan-note/siyuan/kernel < 3.7.4`

## Remediation

Refer to the advisory for the patched release.
