Name of the Vulnerable Software and Affected Versions NotificationX plugin for WordPress versions through 3.1.11

Description The NotificationX plugin for WordPress has a flaw that allows unauthorized modification of data. A missing capability check on the ''regenerate'' and ''reset'' REST API endpoints allows authenticated attackers with Contributor-level access or higher to reset analytics for any NotificationX campaign, regardless of ownership. The affected API endpoints are ''/wp-json/notificationx/v1/campaigns/{campaign id}/regenerate'' and ''/wp-json/notificationx/v1/campaigns/{campaign id}/reset'', where campaign id represents the ID of the campaign.

Recommendations Update the NotificationX plugin to a version later than 3.1.11.
