CVE-2026-14448Network attack vector

Authenticated command execution via system_certificates injection

Published Jul 20, 2026 · Updated Jul 20, 2026

OS command injection in mbCONNECT24 and myREX24 V2 through 2.20.0 allows remote authenticated users to execute arbitrary system commands. The shared system_certificates view fails to neutralize special elements before constructing an operating-system command. High-privilege portal access is required; successful exploitation permits commands that can read or alter portal data and interrupt mbCONNECT24, mymbCONNECT24, myREX24 V2, or myREX24 V2 Virtual Server.
