CVE-2026-2122Network attack vector

Authenticated SQL injection via demo.php ID parameter

Published Feb 8, 2026 · Updated Feb 8, 2026

SQL injection in XPanel 20260126 and earlier allows remote authenticated users to manipulate database queries through the WAF demo.php endpoint. The endpoint fails to neutralize the ID request argument before SQL processing, although the exact function and query remain undisclosed. Low-privileged panel access and network reachability are required; successful injection permits limited database disclosure, modification, and service interruption.
