Access violation vulnerability in IP Blacklist Cloud 3.43

The IP Blacklist Cloud Plugin for WordPress is a tool that allows users to block certain IP addresses from accessing their website. However, in versions before 3.43, this plugin had a security flaw that allowed attackers with high-level privileges to read the contents of any file on the server. This could expose sensitive information, such as passwords and usernames, to the attackers. Therefore, it is important to update to version 3.43 or higher if you use this plugin.
