Vulnerability Overview

The Elegant Themes Monarch plugin before 1.2.7 for WordPress has 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-269: Improper Privilege Management

Reaching this weakness in Bloom Email Opt-In <= 1.1.0 takes a caller who can reach the endpoint. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Bloom Email Opt-In the fix is 1.1.1: builds <= 1.1.0 are affected, anything from 1.1.1 onward is not.

Remediation

Update to version 1.1.1, 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: Bloom Email Opt-In 1.1.1 closes this, and updating the plugin is the step that ends it.
