CVE-2025-1475Network attack vector

Account takeover via unverified SMS phone number

Published Mar 7, 2025 · Updated Apr 8, 2026

Authentication bypass in WPCOM Member 1.7.5 and earlier allows remote attackers to assume any existing account through SMS login. The SMS-login handler trusts the attacker-controlled user_phone value as the account selector without adequately verifying that number before creating the login session. SMS login must be enabled; successful exploitation grants the selected account's privileges, including Administrator access when that account is targeted.
