# CVE-2026-77876: Control Web Panel (CWP) < 1.16 OS Command Injection via protected_directory

- Exploited (CISA KEV): no
- Published: 2026-11-02
- CVSS: 9.3 CRITICAL (v4.0)
- EPSS: no score
- CWE: CWE-78

Control Web Panel (CWP) before webpanel_version 1.16 contains an OS command injection vulnerability in the protected_directory user panel module that allows attackers to execute arbitrary commands by submitting unescaped input through the file POST parameter in the acc=deletedp action. Attackers can exploit this flaw, which passes attacker-controlled input directly into a shell_exec call, to achieve code execution in the user panel context.

"No public claim" means no vendor statement names this CVE; "Before feed history" means the CVE is older than the vendor feed. In both cases generic rules may still block it.
