Technical details

The vulnerability is a missing capability check in the 'Update_Options' action class's 'do_action' function. Unauthenticated attackers can exploit this via the plugin's form submission mechanism to modify JetEngine Options Page values, provided JetEngine is installed and a form is configured with the Update Options post-submission action. The lack of authentication allows direct manipulation of stored options without proper authorization verification.
