Research Description: WhatsApp contact widgets are small from a user-experience perspective, but they sit on a sensitive boundary between public visitors, business communication flows, tracking, shortcodes, and administrator-controlled display rules. A misstep in this layer can turn a support button into a stored XSS vector, an unsafe redirect path, or a leakage point for contact and form data. Click to Chat – HoliThemes version 4.39 has successfully completed the CleanTalk Plugin Security Certification process and received PSC-2026-64656, confirming that the plugin was reviewed from a secure code perspective with attention to common exploitation paths for communication and front-end widget plugins.
Affected versions: Min 4.39, max 4.39.
Status: SAFE & CERTIFIED
