CVE-2026-5553Public exploitNetwork attack vector

SQL injection via unsanitized Name parameter

Published Apr 5, 2026 · Updated Apr 5, 2026

SQL injection in Online Cellphone System 1.0 allows remote authenticated users to read or modify database data via the Name field. The /cp/available.php handler inserts the multipart Name value directly into an SQL query without validation or parameter binding. Low-privileged network access is required; demonstrated boolean-, error-, and time-based payloads expose query results and timing behavior.
