CVE-2026-9557Network attack vector

Authenticated SSRF via insufficient URL validation

Published May 29, 2026 · Updated May 29, 2026

SSRF in Mautic's Focus component allows remote authenticated users to force server-side HTTP requests to arbitrary destinations. The MauticFocusBundle accepts user-supplied URLs without sufficiently validating the destination before the hosting server initiates the request. Access to the Mautic panel is required; successful exploitation supports internal port probing and network reconnaissance but does not interrupt service.
