CVE-2026-86241

A weakness has been identified in liufee FeehiCMS up to 2.1.1. This impacts an unknown function of the file environments/prod/backend/config/main-local.php of the component Cookie Validation. This manipulation of the argument cookieValidationKey causes use of hard-coded cryptographic key . The attack is possible to be carried out remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
