Unauthenticated private-content disclosure via open REST endpoint
Published Apr 29, 2026 · Updated Apr 29, 2026
Missing authorization in Complianz GDPR/CCPA Cookie Consent Banner 7.4.5 and earlier allows remote attackers to read unpublished consent-area content. The consent-area REST route accepts every request, while cmplz_rest_consented_content() returns block content without checking post status or read permission. No authentication is required, and disclosure is limited to consent-area block content in private, draft, or unpublished posts.
