Summary
The Popup Maker plugin for WordPress up to version 1.22.0 contains an authorization bypass vulnerability. It allows authenticated attackers with editor-level access or higher to install and activate arbitrary plugins from an external URL, leading to remote code execution.
Risk Assessment
The risk for the organization includes potential takeover of the WordPress site through remote code execution. The attack requires an active Popup Maker Pro license and the absence of Popup Maker Pro installation, which limits but does not eliminate the threat for sites meeting these conditions.
Recommendation
Immediately update the Popup Maker plugin to the latest available version. Also verify if the site has an active Popup Maker Pro license without the Pro component installed, and either install it or deactivate the license.
Other vulnerabilities in Popup Maker
Original NVD description (English source)
The Popup Maker – Boost Sales, Conversions, Optins, Subscribers with the Ultimate WP Popup Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.22.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with editor-level access and above, to install and activate an arbitrary plugin from an attacker-controlled URL, leading to remote code execution. Exploitation requires that a valid Popup Maker Pro license is active on the target site and that Popup Maker Pro is not yet installed, as these conditions are necessary for the legacy v1/connect/info endpoint to issue the bearer token used to satisfy the install endpoint's only non-spoofable validation check.
