Stored Cross-Site Scripting Vulnerability in Responsive Flickr Slideshow Plugin for WordPress

CVE-2024-13660

Summary

The Responsive Flickr Slideshow plugin for WordPress is prone to a Stored Cross-Site Scripting vulnerability through the 'fshow' shortcode. This issue arises from inadequate input sanitization and output escaping of user-supplied attributes. As a result, authenticated attackers with contributor-level access can insert malicious scripts in the pages, which can then execute when users visit the compromised page. Immediate awareness and patches are crucial for maintaining security in affected WordPress environments.
