EUVD-2026-110495
Kener 3.0.0 before 4.1.10 contains an authentication bypass vulnerability that allows unauthenticated attackers to forge session tokens by using the hardcoded DUMMY_SECRET fallback key. When KENER_SECRET_KEY is empty or unset, attackers knowing an administrator email can sign a kener-user cookie to access /manage/api with full administrative privileges or forge password-reset tokens.
