CVE-2026-59834: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in siyuan-note siyuan
SiYuan, an open-source personal knowledge management system, has a SQL injection vulnerability in versions prior to 3.7.1. The issue exists in the block search endpoint POST /api/search/fullTextSearchBlock, where attacker-controlled path values are concatenated into SQL predicates in non-SQL search modes. This allows an unauthenticated visitor to inject a UNION SELECT statement and retrieve rows from hidden documents by exploiting visible box and path projections. The vulnerability is fixed in version 3.7.1.
AI Analysis
Technical Summary
CVE-2026-59834 is a SQL injection vulnerability in SiYuan prior to version 3.7.1. The vulnerability arises because the block search endpoint concatenates attacker-controlled path values directly into SQL predicates used by non-SQL search modes. This flaw permits an unauthenticated publish visitor to perform a UNION SELECT injection, enabling access to rows from hidden documents by leveraging allowed visible box and path projections. The issue is resolved in version 3.7.1.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to inject SQL commands via the block search endpoint, allowing them to access data from hidden documents that should not be visible. The vulnerability impacts confidentiality but does not affect integrity or availability. The CVSS score is 7.5 (high severity), reflecting the ease of remote exploitation without authentication and the high impact on data confidentiality.
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 vendor advisory was provided to indicate alternative mitigations or temporary fixes.
