    Published: 2 Oct 2023Last Modified: 10 Jun 2026

    Summary:

    Details: An issue was discovered in pretix before 2023.7.1. Incorrect parsing of configuration files causes the application to trust unchecked X-Forwarded-For headers even though it has not been configured to do so. This can lead to IP address spoofing by users of the application.
