## Technical details

A stored cross-site scripting (XSS) vulnerability exists in Statamic CMS within the 'automagic' form notification email component. The root cause is the failure to escape user-provided input before rendering it in the HTML email template sent to administrators. An unauthenticated remote attacker can exploit this by submitting a form containing malicious HTML/JavaScript. When a recipient (typically an administrator) views the notification email in a client that renders HTML, the payload executes in the context of the recipient's session. This has been patched in versions 5.74.3 and 6.24.2.
