Technical Analysis
CVE-2026-60083 describes an incorrect authorization vulnerability in SiYuan note-taking software prior to version 3.8.0. The MCP file tool's path blocklist is incomplete, allowing authenticated administrators to bypass intended restrictions and access sensitive workspace files through the HTTP API. Specifically, attackers can read plaintext passwords stored in data/.siyuan/publishAccess.json and access other sensitive files such as data/templates and data/snippets/conf.json.
Potential Impact
Authenticated administrators can read plaintext publish-mode passwords and access other sensitive configuration files, potentially compromising workspace security and confidentiality. The vulnerability requires administrator privileges and does not allow privilege escalation or remote unauthenticated access.
Mitigation Recommendations
Upgrade SiYuan to version 3.8.0 or later where this authorization issue is fixed. Since the vulnerability affects versions prior to 3.8.0, applying the official update is the recommended remediation. No information about alternative mitigations or temporary fixes is provided.
