CVE-2026-59834: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in siyuan-note siyuan
SiYuan is an open-source personal knowledge management system. Prior to 3.7.1, the block search endpoint POST /api/search/fullTextSearchBlock concatenates attacker-controlled paths values into SQL predicates used by non-SQL search modes, allowing an unauthenticated publish visitor to inject a UNION SELECT and return rows from hidden documents by projecting an allowed visible box and path. This issue is fixed in versions 3.7.1.
AI Analysis
Technical Summary
CVE-2026-59834 is a SQL injection vulnerability (CWE-89) in SiYuan versions before 3.7.1. The vulnerability exists in the POST /api/search/fullTextSearchBlock endpoint, which improperly concatenates attacker-controlled path values into SQL predicates used by non-SQL search modes. This allows an unauthenticated publish visitor to perform a UNION SELECT injection and retrieve data from hidden documents by leveraging visible box and path projections. The issue is resolved in version 3.7.1.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to perform SQL injection via the block search endpoint, potentially exposing sensitive data from hidden documents. The vulnerability impacts confidentiality but does not affect integrity or availability. The CVSS 3.1 base score is 7.5 (high severity), reflecting network attack vector, low attack complexity, no privileges required, no user interaction, and high confidentiality impact.
Mitigation Recommendations
A fix is available in SiYuan version 3.7.1. Users should upgrade to version 3.7.1 or later to remediate this vulnerability. No additional vendor advisory details are available, so patching is the recommended mitigation.
