CVE-2026-59853: CWE-862: Missing Authorization in siyuan-note siyuan
SiYuan versions prior to 3.7.1 contain a missing authorization vulnerability in the /api/storage/getCriteria endpoint. This endpoint returns saved search criteria without applying the publish-access filtering that other storage endpoints enforce. As a result, a user with publish-mode Reader privileges can access private document paths, notebook, document, and block IDs, as well as search and replace keywords for unpublished documents. This issue is fixed in version 3.7.1.
AI Analysis
Technical Summary
CVE-2026-59853 is a missing authorization vulnerability (CWE-862) in the SiYuan personal knowledge management system. Before version 3.7.1, the /api/storage/getCriteria endpoint does not enforce publish-access filtering, unlike other storage endpoints. This allows a user with limited publish-mode Reader privileges to retrieve sensitive information including private document paths, notebook, document, and block identifiers, and search/replace keywords related to unpublished documents. The vulnerability is resolved in version 3.7.1.
Potential Impact
An attacker with publish-mode Reader privileges can access private and unpublished document metadata and search criteria that should be restricted. This exposure could lead to unauthorized disclosure of sensitive document structure and content metadata. The vulnerability does not affect document content integrity or availability, but confidentiality is impacted.
Mitigation Recommendations
Upgrade SiYuan to version 3.7.1 or later, where the missing authorization check on the /api/storage/getCriteria endpoint has been fixed. Patch status is confirmed by the vendor stating the issue is resolved in 3.7.1. No other mitigations are indicated.
