Executive Summary

The vulnerability in the NotificationX WordPress plugin allows authenticated users with Contributor-level access or higher to modify data without proper authorization. Specifically, due to missing capability checks on the 'regenerate' and 'reset' REST API endpoints, these users can reset analytics for any NotificationX campaign, even if they do not own the campaign.

Impact Analysis

This vulnerability can impact you by allowing unauthorized users with Contributor-level access or above to reset analytics data for any NotificationX campaign. This could lead to loss or manipulation of important campaign analytics data, potentially affecting marketing insights and decision-making.

Mitigation Strategies

Update the NotificationX WordPress plugin to a version later than 3.1.11 where the missing capability checks on the 'regenerate' and 'reset' REST API endpoints have been fixed. Restrict Contributor-level access or higher to trusted users only until the update is applied. [2]
