At a glance

CVE-2020-7055 is a high-severity Missing Authorization vulnerability in the Elementor Website Builder WordPress plugin, affecting versions < 2.7.5. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 2.7.5; sites on affected versions should update now. Disclosed October 2019, reported by Sam Thomas.

Vulnerability Overview

The Elementor Website Builder plugin for WordPress is vulnerable to arbitrary file upload by subscriber level users and above due to missing authorization on the Import Templates function, which makes it possible for attackers to gain remote code execution. This affects versions up to 2.7.5.

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 < 2.7.5 takes a caller who can reach the endpoint. 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 the fix is 2.7.5: builds < 2.7.5 are affected, anything from 2.7.5 onward is not.

Remediation

Update to version 2.7.5, 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 2.7.5 closes this, and updating the plugin is the step that ends it.
