CVE-2026-1804

Name of the Vulnerable Software and Affected Versions WDES Responsive Popup plugin for WordPress versions prior to 1.3.7

Description The WDES Responsive Popup plugin for WordPress is susceptible to Stored Cross-Site Scripting through the 'wdes-popup-title' shortcode. Insufficient input sanitization and output escaping on user-supplied attributes allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These scripts will execute when a user accesses the affected page.

Recommendations Update the WDES Responsive Popup plugin to version 1.3.7 or later.
