What is CVE-2026-77876?

An OS command injection vulnerability has been identified in Control Web Panel (CWP) prior to version 1.16. This flaw resides in the protected_directory user panel module, which enables attackers to execute arbitrary commands by supplying unescaped input via the file POST parameter during the acc=deletedp action. The vulnerability allows attacker-controlled input to be passed directly into a shell_exec call, facilitating unauthorized code execution within the context of the user panel. This presents a significant risk for systems utilizing vulnerable versions of CWP, highlighting the importance of patching to safeguard against potential exploits.
