Input validation vulnerability in Crony Cronjob Manager 0.5.0

The Crony Cronjob Manager plugin for WordPress has a security issue that could be exploited by hackers. This can happen in any version up to version 0.5.0. The problem is that the plugin does not properly check for a special code meant to prevent attacks. As a result, attackers who are not logged in to the website can trick the site administrator into unknowingly performing an action, such as clicking on a link. We do not know the full extent of the damage this vulnerability can cause.
