Duplicate Advisory: Missing authorization on refreshBacklink allows anonymous readers to trigger persistent server-side writes and unauthenticated resource amplification (publish mode)
Summary
## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-wgwx-479j-23vq. This link is maintained to preserve external references. ## Original Description SiYuan versions before v3.7.4 contain a missing authorization vulnerability in the /api/ref/refreshBacklink endpoint that allows anonymous readers to trigger persistent server-side writes. Attackers can invoke the endpoint with an attacker-controlled block ID to flush transaction queues, scan all references globally, and enqueue database writes, bypassing read-only protections and enabling resource amplification attacks.
