What is CVE-2024-12457?

The Chat Support for Viber plugin for WordPress is susceptible to Stored Cross-Site Scripting (XSS) due to inadequate input sanitization and output escaping. This vulnerability arises in the 'vchat' shortcode, allowing attackers with contributor-level access and higher to inject malicious web scripts. 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.
