CVE-2026-4302, 21 Mar 2026
The WowOptin: Next-Gen Popup Maker plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.4.29. This is due to the plugin exposing a publicly accessible REST API endpoint (optn/v1/integration-action) with a permission_callback of __return_true that passes user-supplied URLs directly to wp_remote_get() and wp_remote_post() in the Webhook::add_subscriber() method without any URL validation or restriction. The plugin does not use wp_safe_remote_get/post which provide built-in SSRF protection. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application, which can be used to query and modify information from internal services.

CVE-2026-1720, 5 Mar 2026
The WowOptin: Next-Gen Popup Maker - Create Stunning Popups and Optins for Lead Generation plugin for WordPress is vulnerable to unauthorized arbitrary plugin installation due to a missing capability check on the 'install_and_active_plugin' function in all versions up to, and including, 1.4.24. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install and activate arbitrary plugins. CVE record

What to do if you run WowOptin

If you run WowOptin, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.

If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
