Advanced Responsive Video Embedder 10.8.7/10.8.8 - Hardcoded Backdoor Authentication Bypass

CVE-2026-18072
Verified

Description

The compromised Advanced Responsive Video Embedder WordPress plugin releases 10.8.7 and 10.8.8 accept a hardcoded token through the `_wplogin` parameter and establish an authenticated administrator session before normal authentication. A single unauthenticated GET request triggers the backdoor. This template only inspects the redirect and session-cookie response and does not perform any administrative action.
