Medium (5.4). EPSS 0.3% chance of exploitation in the next 30 days.
The PopupKit plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.2.0. This is due to the plugin not properly verifying that a user is authorized to access the /popup/logs REST API endpoint. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read and delete analytics data including device types, browser information, countries, referrer URLs, and campaign metrics.
