CVE-2026-5675Public exploitNetwork attack vector

Authenticated SQL injection via unsanitized emp parameter

Published Apr 6, 2026 · Updated Apr 6, 2026

SQL injection in Construction Management System 1.0 allows remote authenticated users to alter database queries via the emp parameter. The borrowed_tool.php handler passes the emp value into an SQL query without sanitization or validation, permitting injected SQL syntax to change query execution. A valid application account is required; the public proof of concept demonstrates time-based blind execution with a SLEEP expression, while database permissions bound accessible data and operations.
