Description

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.
