CyberRota Analysis
AI-GeneratedThe Dear Flipbook plugin for WordPress is vulnerable to stored cross-site scripting due to inadequate input sanitization in the 'post_content' parameter, affecting all versions up to 2.4.30. This vulnerability allows authenticated users with contributor-level access or higher to inject malicious scripts into pages, which can execute when other users access those pages. WordPress site administrators and developers using this plugin should prioritize patching or updating to mitigate potential exploitation risks.
Original NVD Description
The Dear Flipbook – PDF Flipbook, 3D Flipbook, PDF embed, PDF viewer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'post_content (Custom HTML block inner HTML)' parameter in all versions up to, and including, 2.4.30 due to insufficient input sanitization and output escaping. 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. A Contributor-level attacker can insert a crafted .df-element div with data-df-lightbox='thumb' via a Custom HTML block, whose inner HTML is passed as the title argument to parseThumbs() at render time, enabling both innerHTML injection into a span element and attribute breakout via an onerror handler on a constructed img element.
