While only authenticated users with Contributor-level permissions or higher can exploit it, the potential consequences include unauthorized access to sensitive data and further site manipulation. This makes the vulnerability a serious concern for websites with multiple contributors or administrators.

To fix the vulnerability, you need to update the Beaver Builder – WordPress Page Builder plugin to version 2.8.3.6 or later.

If you don’t update the plugin, your site remains vulnerable to Stored XSS attacks, where malicious scripts can be injected by users with Contributor-level permissions or higher. These scripts can be used to steal user data, hijack sessions, or perform unauthorized actions on your website. The longer the plugin is left unpatched, the more exposed your site is to potential attacks.

Question 5
