Summary

The Chat Support for Viber plugin for WordPress is susceptible to Stored Cross-Site Scripting (XSS) due to inadequate input sanitization and output escaping.

These scripts can execute whenever a victim accesses an affected page, leading to potential data breaches and user impersonation risks. Users are advised to update to the latest version of the plugin to mitigate these threats.
