The Popup Maker – Boost Sales, Conversions, Optins, Subscribers with the Ultimate WP Popup Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via values[Name] Parameter in all versions up to, and including, 1.24.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The wp_kses sanitization applied on output is insufficient in this context because HTML entities within allowed attribute values survive normalization intact and are later evaluated by the jQuery(link.attr('href')) sink in wp-admin/js/common.js when a contextual help tab anchor is clicked.
The Popup Maker plugin for WordPress up to version 1.24.0 contains a stored cross-site scripting (XSS) vulnerability via the post_title field. Authenticated users with contributor-level access or higher can inject malicious scripts into post titles, which are later executed in users' browsers when viewing affected pages. This occurs due to insufficient input sanitization and output escaping, allowing HTML entity-encoded payloads to bypass sanitization and execute via the Select2 component.
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 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.
