What is CVE-2025-10745?
CVE-2025-10745 is a medium-severity vulnerability in specialk Banhammer – Monitor Site Traffic, Block Bad Users and Bots, published on 26 Sep 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-330
