Summary

Duplicate Advisory: Non-administrator responses from /api/system/getConf omit three secrets that the configuration-export path explicitly strips, disclosing the session-cookie signing key and the OS username to anonymous readers

Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-h4v5-crx2-3cv4. This link is maintained to preserve external references.

Original Description

SiYuan versions before v3.7.4 fail to mask sensitive configuration fields in the /api/system/getConf endpoint, allowing anonymous or publish-reader users to obtain the session-cookie signing key, OS username via pandoc path, and encrypted-notebook key material. Attackers can forge and tamper with session cookies to impersonate users, and on instances without access-auth codes configured, escalate to administrator privileges.
