Researcher István Márton - Wordfence

Description

The Anti Hacker plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the antihacker_install_plugin() function in versions up to, and including, 4.19. This makes it possible for authenticated attackers with minimal permission, such as a subscriber, to install arbitrary plugins on the vulnerable site. This could be used to install additional vulnerable plugins that could aid in further compromise of the site.
