CVE-2025-30006Public exploitNetwork attack vector

Browser script execution via reflected class parameter

Published Mar 31, 2025 · Updated Nov 28, 2025

Reflected XSS in Xorcom CompletePBX 5.11.23 and earlier allows remote attackers to execute script in an administrator's browser. The administrative control panel inserts the class query parameter into an HTML response without sanitization or context-appropriate output encoding. Exploitation requires an administrator to open a crafted URL; injected script then runs within that user's CompletePBX browser session.
