What exactly is the vulnerability in the All In One WP Security plugin?

The vulnerability allows an attacker to bypass protections that obscure and rename the WordPress login page. By exploiting an input sanitization issue, the normal wp-login.php page can be accessed directly even if renamed. This defeats the security benefit of hiding the login location from brute force attacks.

Question 2

How serious is this vulnerability? Does it put my site at risk?

How serious is this vulnerability? Does it put my site at risk?

This vulnerability is quite serious. If attackers can freely access the login page, it enables unlimited password guessing attempts. Even strong passwords could eventually be cracked through brute force. Once logged in, the attacker would have admin access to steal data, infect sites with malware, or cause other types of compromise.

Question 3

What versions of the plugin are affected?

Accepted Answer

What versions of the plugin are affected?

All versions up to and including 5.2.4 are impacted. The issue was introduced due to a change in the loginURL hook. Versions since 5.2.5 contain the patched code to properly sanitize input and prevent the protection bypass.

Question 7
