Unauthenticated access to protected information

Published Apr 8, 2026 · Updated Apr 8, 2026

Missing authorization in G5Theme Book Previewer for Woocommerce 1.0.6 and earlier allows remote attackers to read protected information. Neither Patchstack nor the public CVE record identifies the affected endpoint, function, or resource, so the precise missing check is undisclosed. Unauthenticated access is sufficient, but the undisclosed resource prevents a more specific assessment of the exposed data.
