CVE-2026-5147Public exploitNetwork attack vector

Database data extraction via unescaped website parameter

Published Mar 30, 2026 · Updated Mar 30, 2026

SQL injection in YunaiV yudao-cloud 2026.01 allows remote attackers to extract database data through the get-by-website tenant endpoint. The TenantMapper.selectListByWebsite method places the website value into a MyBatis apply expression that builds a FIND_IN_SET SQL predicate without safe binding. The endpoint permits anonymous requests, and response differences provide a boolean oracle for extracting database contents.
