CVE-2026-6978Public exploitNetwork attack vector

Database manipulation via decoded sqls parameter

Published Apr 25, 2026 · Updated Apr 25, 2026

SQL injection in JiZhiCMS 2.5.0 through 2.5.6 allows remote authenticated users to read or alter database data via the sqls parameter. The addcache.html administrative handler passes sqls through htmlspecialchars_decode and uses the decoded value in an SQL command without neutralizing SQL metacharacters. High-privilege administrative access is required; successful exploitation affects database confidentiality, integrity, and availability.
