AI-suggested
Upgrade Kener to version 4.1.10 or later, where this vulnerability is fixed. Ensure that the KENER_SECRET_KEY environment variable is properly set and not left empty or unset to avoid fallback to the hardcoded DUMMY_SECRET key.
Description
Kener versions 3.0.0 up to but not including 4.1.10 contain a critical authentication bypass vulnerability due to the use of a hard-coded cryptographic key fallback. If the environment variable KENER_SECRET_KEY is empty or unset, attackers who know an administrator's email can forge session tokens and gain full administrative access or create password-reset tokens. This flaw is fixed in version 4.1.10.
