At a glance

CVE-2023-3124 is a high-severity Missing Authorization vulnerability in the Elementor Website Builder Pro WordPress plugin, affecting versions <= 3.11.6. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 3.11.7; sites on affected versions should update now. Disclosed March 2023, reported by Jerome Bruandet.

Vulnerability Overview

The Elementor Pro plugin for WordPress is vulnerable to unauthorized data modification due to a missing capability check on the update_page_option function in versions up to, and including, 3.11.6. This makes it possible for authenticated attackers with subscriber-level capabilities to update arbitrary site options, which can lead to privilege escalation.

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-862: Missing Authorization

Reaching this weakness in Elementor Website Builder Pro <= 3.11.6 takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Elementor Website Builder Pro the fix is 3.11.7: builds <= 3.11.6 are affected, anything from 3.11.7 onward is not.

Remediation

Update to version 3.11.7, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Elementor Website Builder Pro 3.11.7 closes this, and updating the plugin is the step that ends it.
