# Mautic: form submission endpoint redirects visitors to arbitrary external sites

The public form submission endpoint (/form/submit) in Mautic redirects the visitor to a return address supplied with the submission without checking that it stays on a trusted host. An attacker can use a legitimate Mautic domain to send visitors to phishing or malware sites.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

An Open Redirect vulnerability exists in the public form submission endpoint (/form/submit) of Mautic. After a form is submitted, the application redirects the visitor to a return address supplied with the submission without verifying that it points to the Mautic instance or another trusted host. An unauthenticated attacker can exploit this to send visitors from a legitimate Mautic domain to an arbitrary external website, for example to phishing pages that imitate the original landing page or to sites that deliver malware. Any Mautic instance with a published form is affected. Exploitation requires the victim to submit a form prepared by the attacker.
