CVE-2025-12094

The OOPSpam Anti-Spam: Spam Protection for WordPress Forms & Comments (No CAPTCHA) plugin for WordPress is vulnerable to IP Header Spoofing in all versions up to, and including, 1.2.53. This is due to the plugin trusting client-controlled forwarded headers (such as CF-Connecting-IP, X-Forwarded-For, and others) without verifying that those headers originate from legitimate, trusted proxies. This makes it possible for unauthenticated attackers to spoof their IP address and bypass IP-based security controls, including blocked IP lists and rate limiting protections, by sending arbitrary HTTP headers with their requests.

Summary		(es) El plugin OOPSpam Anti-Spam: Protección contra correo no deseado para formularios y comentarios de WordPress (sin CAPTCHA) para WordPress es vulnerable a la Suplantación de encabezados IP en todas las versiones hasta la 1.2.53, inclusive. Esto se debe a que el plugin confía en encabezados reenviados controlados por el cliente (como CF-Connecting-IP, X-Forwarded-For y otros) sin verificar que esos encabezados se originen de proxies legítimos y de confianza. Esto hace posible que atacantes no autenticados suplanten su dirección IP y eludan los controles de seguridad basados en IP, incluyendo listas de IP bloqueadas y protecciones de limitación de velocidad, enviando encabezados HTTP arbitrarios con sus solicitudes.
