Technical details
The vulnerability is a cross-site scripting (XSS) flaw in RTMKit versions 2.1.5 and earlier that requires no authentication to trigger. The attack involves injecting malicious JavaScript that executes in the context of affected web pages when visited by users. While user interaction is required (e.g., clicking a link or visiting a crafted page), the lack of authentication requirement makes this a network-accessible threat. Attackers can harvest session tokens, redirect visitors to phishing sites, or perform actions on behalf of logged-in users. The vulnerability has been patched in version 2.1.6.
