Vulnerability Overview

The Happy Addons for Elementor plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to 3.10.0 (exclusive). This makes it possible for authenticated attackers, with contributor access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-918: Server-Side Request Forgery (SSRF)

Reaching this weakness in Happy Addons for Elementor < 3.10.0 takes a caller who can reach the endpoint. Server-side request forgery means the application fetches a URL supplied by the caller, turning the server into a proxy for requests the attacker could not make directly.

The request originates from inside the hosting network, which is how these flaws reach cloud metadata endpoints, internal admin panels and services that trust local traffic. For Happy Addons for Elementor the fix is 3.10.0: builds < 3.10.0 are affected, anything from 3.10.0 onward is not.

Remediation

Update to version 3.10.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Happy Addons for Elementor: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Happy Addons for Elementor 3.10.0 closes this, and updating the plugin is the step that ends it.
