Vulnerability Overview

The Premium Addons for Elementor plugin for WordPress is vulnerable to Regular Expression Denial of Service (ReDoS) in all versions up to, and including, 4.10.35. This is due to processing user-supplied input as a regular expression. This makes it possible for authenticated attackers, with Author-level access and above, to create and query a malicious post title, resulting in slowing server resources.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user.

CWE-400: Uncontrolled Resource Consumption

Reaching this weakness in Premium Addons for Elementor <= 4.10.35 takes a caller who can reach the endpoint. Uncontrolled resource consumption means a request can make the server do an amount of work it never bounds, because the size or repetition of the job is taken from the request rather than capped by the code.

A single caller can hold PHP workers, database connections or disk open long enough to slow the site for everyone, without needing any account or any other flaw. For Premium Addons for Elementor the fix is 4.10.36: builds <= 4.10.35 are affected, anything from 4.10.36 onward is not.

Remediation

Update to version 4.10.36, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Premium Addons for Elementor: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Premium Addons for Elementor 4.10.36 closes this, and updating the plugin is the step that ends it.
