CVE-2026-18072Public exploitNetwork attack vector

Unauthenticated administrator takeover via hardcoded request token

Published Jul 29, 2026 · Updated Jul 29, 2026

Authentication bypass in Advanced Responsive Video Embedder 10.8.7 through 10.8.8 allows remote attackers to obtain administrator access. The _arve_uc_init() handler treats a request-controlled _wplogin or _wpm value matching a source-embedded SHA-256 constant as sufficient authentication. No account or user interaction is required; a matching token creates a persistent session for an existing administrator and exposes full site administration.
