CVE-2023-23990 is a high-severity Incorrect Privilege Assignment vulnerability in the Redirection for Contact Form 7 WordPress plugin, affecting versions <= 2.7.0. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact).

Vulnerability Overview

The Redirection for Contact Form 7 plugin is vulnerable to Authenticated Privilege Escalation in versions up to, and including, 2.7.0 due to the ability to update usermeta information. This allows authenticated attackers with Editor-level permissions and above to modify their permissions and grant themselves administrator privileges.

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-266: Incorrect Privilege Assignment

A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.

Remediation

Update to version 2.8.0, 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: Redirection for Contact Form 7 2.8.0 closes this, and updating the plugin is the step that ends it.
