CVE-2026-4302

CVSS v3.1

7.2

High

AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N
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.
