CVE-2022-25772Network attack vector

Stored XSS via unescaped tracking User-Agent metadata

Published Jun 20, 2022 · Updated Aug 3, 2024

Stored XSS in Mautic before 4.3.0 allows remote attackers to inject JavaScript through tracking-request User-Agent metadata. The email event timeline template outputs the stored useragent field without escaping it, allowing request metadata to become executable page content. Execution requires an authorized user to open the affected tracking timeline, where the script runs in that user's browser and can read or alter data available to the page.
