AI Analysis

Impact

This vulnerability is an unauthenticated Cross Site Scripting flaw located in the Notification for Telegram plugin for WordPress. Versions 3.5.2 and earlier fail to sanitize user input, allowing an attacker to inject arbitrary JavaScript that executes in the browser of any visitor viewing a page that renders the vulnerable content.

Affected Systems

WordPress sites running the Rainafarai Notification for Telegram plugin at version 3.5.2 or earlier are vulnerable; upgrading to version 3.5.3 or later removes the flaw.

Risk and Exploitability

The CVSS base score of 7.1 indicates high severity. The EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog. Because the flaw is unauthenticated, any site visitor can trigger it, making the potential for exploitation straightforward, though widespread incidents have not yet been confirmed.
