 "title": "Real3D Flipbook – 3D FlipBook, PDF FlipBook, PDF Viewer, PDF Embedder <= 5.5 - Unauthenticated DOM-Based Cross-Site Scripting via 'r3d-' URL Parameters",
 "description": "The Real3D Flipbook plugin for WordPress is vulnerable to DOM-Based Cross-Site Scripting via 'r3d-' prefixed URL parameters in all versions up to, and including, 5.5. This is due to the front-end embed script copying any 'r3d-<option>' query parameter into the flipbook options without validation, so HTML-bearing options reach innerHTML sinks in the viewer. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when they trick a user into opening a crafted link to a page containing a flipbook.",
