The vulnerability in the Dear Flipbook – PDF Flipbook, 3D Flipbook, PDF embed, PDF viewer plugin for WordPress is a Stored Cross-Site Scripting (XSS) issue.

An attacker with Author-level access can inject malicious code that runs when other users view the infected pages. This can result in theft of user credentials, session hijacking, defacement, or other malicious actions that compromise the security and integrity of the website and its users.
