Vulnerability from fkie_nvd - Published: 2026-07-09 23:17 - Updated: 2026-10-25 15:10
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
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.
