CVE-2026-72793

siyuan-note / siyuan

9.2 · CVSS 4.0Critical

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.
