CVE-2025-5257Network attack vector

Unauthenticated draft disclosure via unchecked preview routes

Published May 28, 2025 · Updated May 28, 2025

Improper access control in Mautic allows remote attackers to read unpublished page content via predictable preview URLs. The /page/preview/{id} route accepts sequential page identifiers and returns unpublished content without enforcing preview permission checks. No authentication or user interaction is required; exposure is limited to draft content reachable through guessed identifiers, which search engines can also index.
