Description
The Click to Chat – WA Widget plugin for WordPress (by HoliThemes) up to version 4.38 is vulnerable to stored cross-site scripting (XSS) via the 'num' parameter in the [chat] shortcode. This occurs because user input is insufficiently escaped when embedded inside JavaScript string literals within HTML event-handler attributes, allowing an attacker with Contributor-level access or higher to inject arbitrary scripts that execute when users click the WhatsApp chat button.
