CVE-2026-40825Network attack vector

Database disclosure via accountstatus devices SQL injection

Published May 27, 2026 · Updated May 27, 2026

SQL injection in myREX24 V2 and mbCONNECT24 portal variants 2.20.0 and earlier allows remote authenticated users to read the database. The accountstatus view places the devices parameter into an SQL UPDATE command without neutralizing SQL control characters. High application privileges are required; successful injection exposes the entire database and permits changes only in a noncritical table.
