At a glance

CVE-2024-3599 is a medium-severity Missing Authorization vulnerability in the WPLP Cookie Consent WordPress plugin, affecting versions <= 3.0.2. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 3.1.0; sites on affected versions should update now. Disclosed April 2024, reported by Krzysztof Zając.

Vulnerability Overview

The WP Cookie Consent ( for GDPR, CCPA & ePrivacy ) plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the gdpr_policy_process_delete() function in all versions up to, and including, 3.0.2. This makes it possible for unauthenticated attackers to delete arbitrary posts.

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 privileges on the target site, and no interaction from a victim user.

CWE-862: Missing Authorization

WPLP Cookie Consent <= 3.0.2 carries this weakness at gdpr_policy_process_delete(), and reaching it takes no account at all. 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 WPLP Cookie Consent the fix is 3.1.0: builds <= 3.0.2 are affected, anything from 3.1.0 onward is not.

Remediation

Update to version 3.1.0, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: WPLP Cookie Consent 3.1.0 closes this, and updating the plugin is the step that ends it.
