Summary
Mautic core from 7.0.0 before 7.2.2 has a stored cross-site scripting flaw (CWE-79) in the contact detail view. Values of HTML-type custom contact fields are shown without output sanitization. A user or integration able to write to such a field can store a script that runs in the browser of anyone who opens that contact, including an administrator. The script could perform administrative actions, such as creating administrator accounts, or access contact and campaign data.

Description from the CNA
A stored Cross-Site Scripting (XSS) vulnerability exists in the contact detail view of Mautic 7. Values of HTML-type custom contact fields are rendered without output sanitization. A user or integration able to write a value to such a field (for example, through contact editing, the contact API, or a form submission mapped to the field) can store a script payload in it. When another user, including an administrator, opens the affected contact's detail page, the injected script executes within the context of their active browser session. This could allow an attacker to perform administrative actions on behalf of the victim, such as creating new administrator accounts, altering system configuration, or accessing contact and campaign data.
