CVE-2026-12663: Missing authentication for critical function vulnerability

A security issue exists within ControlFLASH™, where the installer grants write permissions to the "Everyone" group on a product installation directory. This could allow arbitrary code execution, resulting in an attacker being given the ability to run any commands or code of the attacker's choice on a target machine at the logged-in user's permission level.
