Source Advisory Statement

## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-34fj-mwm6-fjfg. This link is maintained to preserve external references. ## Original Description siyuan versions before v3.7.4 expose the session cookie signing key through the /api/system/getConf endpoint to unauthenticated users in publish mode. Attackers can retrieve the CookieKey value and forge valid session cookies to impersonate users or gain administrative access.
