Wordfence advisory

medium · CVSS 5.3

The PDFDraft – Drag & Drop PDF Builder, PDF Viewer, Embed & Download PDF, Certificate & Invoice Designer plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the serveTemplatePdfAjax() function and the serveTemplatePdf() REST route (which is registered with `permission_callback => '__return_true'`) in versions up to, and including, 1.1.0. This makes it possible for unauthenticated attackers to download stored template PDFs — which may contain customer PII, invoice, order, and certificate data — by requesting the publicly registered admin-ajax action `pdfdraft_embed_pdf` or the REST endpoint `/wp-json/pdfdraft/v1/embed-pdf/templates/{slug}/pdf` with a known or guessable design slug, bypassing the plugin's own .
