## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-c8w8-3pqp-wr83. This link is maintained to preserve external references.

## Original Description
SiYuan versions before v3.7.4 contain an authentication bypass vulnerability in the WebSocket endpoint caused by differential parsing of query parameters between authentication exemption and session quarantine checks. Unauthenticated attackers can craft a malicious WebSocket URI with duplicated query parameters to bypass access auth code validation and receive the live kernel event stream including document identifiers, titles, and operation logs.

## Affected packages

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

## Remediation

Refer to the advisory for the patched release.
