WordPress · The Dear Flipbook – Pdf Flipbook · CVE-2025-5314
Name of the Vulnerable Software and Affected Versions:
The Dear Flipbook – PDF Flipbook, 3D Flipbook, PDF embed, PDF viewer plugin for WordPress versions up to, and including, 2.3.65
Description:
The issue is related to DOM-Based Reflected Cross-Site Scripting due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts in pages via the `pdf-source` parameter. Attackers can exploit this by tricking a user into performing an action such as clicking on a link.
Recommendations:
For versions up to, and including, 2.3.65, avoid using the `pdf-source` parameter in the affected API endpoint until the issue is resolved.
As a temporary workaround, consider restricting access to the plugin's functionality to minimize the risk of exploitation.
