Input validation vulnerability in Simple Login Log 1.1.3

A plugin called Simple Login Log for WordPress has a security issue in versions 1.1.3 and below. This issue, known as PHP Object Injection, allows attackers who have administrator-level access or higher to insert a harmful piece of code. The vulnerable software does not have any built-in protection against this type of attack. If the target system has another plugin or theme installed that does have protection, the attacker could still potentially delete important files, access private information, or run their own code.
