What is CVE-2026-77880?

An OS command injection vulnerability exists in Control Web Panel before version 1.16. The flaw lies in the loopback API password change endpoint (/newpass/), where unescaped input from the POST 'user' parameter is passed directly to a shell command. This oversight permits an attacker to execute arbitrary OS commands with root privileges, potentially compromising the system's security.

Affected Version(s)

Control Web Panel 0 < 1.16
