CVE-2025-10745
Banhammer – Monitor Site Traffic, Block Bad Users and Bots <= 3.4.8 - Unauthenticated Protection Mechanism Bypass
Description
The Banhammer – Monitor Site Traffic, Block Bad Users and Bots plugin for WordPress is vulnerable to Blocking Bypass in all versions up to, and including, 3.4.8. This is due to a site-wide “secret key” being deterministically generated from a constant character set using md5() and base64_encode() and then stored in the `banhammer_secret_key` option. This makes it possible for unauthenticated attackers to bypass the plugin’s logging and blocking by appending a GET parameter named `banhammer-process_{SECRET}` where `{SECRET}` is the predictable value, thereby causing Banhammer to abort its protections for that request.

Action Type Old Value New Value Added Translation Title: Banhammer - Monitor Site Traffic, Block Bad Users and Bots de specialk, Description: El plugin Banhammer - Monitor Site Traffic, Block Bad Users and Bots para WordPress es vulnerable a una evasión de bloqueo en todas las versiones hasta la 3.4.8, inclusive. Esto se debe a que una 'clave secreta' a nivel de sitio se genera de forma determinista a partir de un conjunto de caracteres constante utilizando md5() y base64_encode(), y luego se almacena en la opción 'banhammer_secret_key'. Esto hace posible que atacantes no autenticados evadan el registro y el bloqueo del plugin añadiendo un parámetro GET llamado 'banhammer-process_{SECRET}', donde '{SECRET}' es el valor predecible, lo que provoca que Banhammer aborte sus protecciones para esa solicitud. -
