Access violation vulnerability in Leyka 3.31.6

The Leyka plugin for WordPress has a security issue that could allow unauthorized people to view sensitive information. This is because the plugin does not have a proper check in place to prevent access to the leyka_ajax_get_campaigns_list() function. This vulnerability affects all versions of the plugin up to and including 3.31.6. As a result, attackers who are logged in with subscriber-level access or higher could potentially view details about campaigns.
