📋 Description

The Defender Security WordPress plugin before 6.4.1 does not verify that the client IP address it derives for its firewall and lockout decisions actually originates from a trusted source, trusting a user-supplied value by default, allowing unauthenticated attackers to spoof their IP address and evade IP-based protections such as login lockout and IP banning, impersonate an allowlisted address, and poison the Defender Security WordPress plugin before 6.4.1's activity logs.
