CVE-2026-15388

Deferred Deferred - Pending Action

Unauthenticated Access to Cookie Consent Settings in WordPress Plugin

Publication date: 2026-08-12

Last updated on: 2026-08-26

Assigner: WPScan

Description

The Cookie Consent WordPress plugin before 0.0.10 does not correctly enforce its intended administrator-only capability check on its consent-settings REST routes, so they fall back to an authentication-only gate, allowing any authenticated user such as a subscriber to update the Cookie Consent WordPress plugin before 0.0.10's consent settings and, on sites connected to the vendor's paid plan, read stored visitor consent logs.

Attack-Flow Graph

Executive Summary

The Cookie Consent WordPress plugin before version 0.0.10 has a flaw where its REST routes do not properly restrict access to administrators. Instead, they only require basic authentication, allowing any logged-in user like a subscriber to modify consent settings. On sites using the vendor's paid plan, these users can also view stored visitor consent logs.

Detection Guidance

Check WordPress plugin versions using the command: wp plugin list. If Cookie Consent is installed and version is below 0.0.10, the system is vulnerable. Inspect REST API routes for unauthorized access by reviewing logs or using tools like WPScan to test endpoints.

Impact Analysis

An attacker with subscriber-level access could change consent settings, potentially violating privacy policies or misleading users. If your site uses the paid plan, they could also access sensitive visitor consent logs, compromising user data privacy.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR or HIPAA by allowing unauthorized access to consent logs and settings, potentially exposing user data without proper consent. It undermines data protection measures required by these regulations.

Mitigation Strategies

Update the Cookie Consent plugin to version 0.0.10 or later immediately. If updating is not possible, consider disabling the plugin temporarily until an update is applied. Review and restrict user roles with access to sensitive settings.
