Summary

Duplicate Advisory: SiYuan: A parser differential between the WebSocket keepalive exemption and the session quarantine allows unauthenticated access to the broadcast event stream, defeating the fix for GHSA-xp2m-98x8-rpj6

Details

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This advisory has been withdrawn because it is a duplicate of GHSA-c8w8-3pqp-wr83.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.
