The issue concerns unauthorized access to unpublished page previews in Mautic, which could be accessed by unauthenticated users and potentially indexed by search engines. This could lead to the unintended disclosure of draft content or sensitive information. The page preview functionality for unpublished content, accessible via predictable URLs (e.g., "/page/preview/1", "/page/preview/2"), lacked proper authorization checks, allowing any unauthenticated user to view content not yet intended for public release.

The upgrade logic in Mautic's application update via an upgrade script is not properly shielded, potentially leading to a vulnerable situation. However, this issue is mitigated by the fact that Mautic must be installed in a specific way to be vulnerable.

The issue is related to a self XSS vulnerability in the notifications within Mautic. Logged in users are vulnerable to this issue, which allows malicious code to be injected into the notification when saving Dashboards.

The default .htaccess file has some restrictions in the access to PHP files to only allow specific PHP files to be executed in the root of the application. However, the regex in the second FilesMatch only checks the filename, not the full path, which is incorrect logic. This issue can enable local host attacks due to an improper validation flaw.
