CVE-2024-13553Network attack vector

Unauthenticated account takeover via Host header spoofing

Published Apr 1, 2025 · Updated Apr 8, 2026

Authentication bypass in Cozy Vision SMS Alert 3.7.9 and earlier allows remote attackers to take over any WordPress account. The OTP login path trusts an attacker-controlled Host header to classify the site as WordPress Playground and assigns the fixed code 1234. No authentication or user interaction is required; a spoofed request can establish a session as any chosen user, including an administrator.
