CVE-2026-5257Public exploitNetwork attack vector

Unauthenticated SQL injection via unsanitized userid

Published Apr 1, 2026 · Updated Apr 1, 2026

SQL injection in Simple Laundry System 1.0 allows remote attackers to access and alter database data through the userid parameter. /delstaffinfo.php inserts the unvalidated userid value directly into a SQL query instead of binding it as data. No login or authorization is required, and crafted GET values support boolean-, error-, time-, and UNION-based database manipulation.
