At a glance

CVE-2024-49271 is a high-severity Improper Control of Generation of Code ('Code Injection') vulnerability in the Unlimited Elements For Elementor WordPress plugin, affecting versions <= 1.5.121. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Editor level or above. The issue is fixed in version 1.5.122; sites on affected versions should update now. Disclosed October 2024, reported by Hakiduck.

Vulnerability Overview

The Unlimited Elements For Elementor (Free Widgets, Addons, Templates) plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.5.121 via the template engine. This is due to the plugin not properly restricting functions that can be called and passed to code execution functions. This makes it possible for authenticated attackers, with Editor-level access and above, to execute code on the server.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-94: Improper Control of Generation of Code ('Code Injection')

Reaching this weakness in Unlimited Elements For Elementor <= 1.5.121 takes an account at Editor level or above. Code injection means input from a request reaches a language construct that evaluates code, so the attacker's text is executed rather than treated as data.

The injected code runs with the web server's privileges, giving the attacker the same access to the database and filesystem as WordPress itself. For Unlimited Elements For Elementor the fix is 1.5.122: builds <= 1.5.121 are affected, anything from 1.5.122 onward is not.

Remediation

Update to version 1.5.122, or a newer patched version

How does WordSec protect against this?

An attacker needs Editor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Unlimited Elements For Elementor 1.5.122 closes this, and updating the plugin is the step that ends it.
