This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is embedded as a Base64-encoded JSON object in a CSS class name on a Custom HTML block; the frontend parseCSSElements() function decodes it client-side with atob() and JSON.parse() and renders the logo property as raw HTML, meaning no server-side or client-side sanitization intercepts the malicious script before DOM insertion.</p> <p><strong>Affected:</strong> dearhive DearFlip – PDF Flipbook, 3D Flipbook, PDF embed, PDF viewer</p> <p>The Dear Flipbook – PDF Flipbook, 3D Flipbook, PDF embed, PDF viewer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the &#39;post_content (class attribute of .dvcss element)&#39; parameter in all versions up to, and including, 2.4.30 due to insufficient input sanitization and output escaping.
