Complianz – GDPR/CCPA Cookie Consent <= 7.4.5 — Missing Authorization to Unauthenticated Private Post Content Disclosure via Consent Area REST Endpoint

Am I affected?

• Check your version: in wp-admin go to Plugins → Installed Plugins and read the version under Complianz GDPR/CCPA Cookie Consent Banner.
• No admin access? Run a passive check of your site. It reads public files only.
• No account is needed to exploit this. Treat any exposed site on an affected version as at risk.

What to do

1. Update to version 7.4.6, or a newer patched version
2. Rotate administrator passwords and application secrets if the site ran a vulnerable version while publicly reachable.
3. Watch Complianz GDPR/CCPA Cookie Consent Banner to get an email when the next vulnerability is published.

Advisory

Source description from Wordfence Intelligence, credited to Wesley van de Kamp.

The Complianz – GDPR/CCPA Cookie Consent plugin for WordPress is vulnerable to unauthorized data access in all versions up to, and including, 7.4.5 This is due to the REST API endpoint at /wp-json/complianz/v1/consent-area/{post_id}/{block_id} using __return_true as the permission_callback, allowing any unauthenticated user to access it. The cmplz_rest_consented_content() function retrieves a post by ID via get_post() and returns the consentedContent attribute of any complianz/consent-area block found in it, without checking if the post is published or if the user has permission to read it. This makes it possible for unauthenticated attackers to read the consent area block content from private, draft, or unpublished posts.
