CVE-2026-17578

Kong Event Gateway versions 1.0.0 through 1.1.1 and 1.2.0 do not enforce key rotation before reaching NIST SP 800-38D recommended usage limit for AES-GCM encryption keys with random nonces when the AWS IAM encryption feature is enabled. If a producer sends messages at a sustained high rate without key rotation, which only occurs on reboot of the Kong Event Gateway instance, the probability of a nonce collision becomes non-negligible. An authorized consumer who detects a nonce collision can recover parts of plaintext from the affected messages. New versions 1.1.2 and 1.2.1 enforce automatic key rotation before the recommended usage limit is reached.

Summary		(es) Las versiones 1.0.0 a 1.1.1 y 1.2.0 de Kong Event Gateway no aplican la rotación de claves antes de alcanzar el límite de uso recomendado por NIST SP 800-38D para claves de cifrado AES-GCM con nonces aleatorios cuando la función de cifrado de AWS IAM está habilitada. Si un productor envía mensajes a una tasa alta y sostenida sin rotación de claves, lo que solo ocurre al reiniciar la instancia de Kong Event Gateway, la probabilidad de una colisión de nonce se vuelve no despreciable. Un consumidor autorizado que detecta una colisión de nonce puede recuperar partes del texto sin cifrar de los mensajes afectados. Las nuevas versiones 1.1.2 y 1.2.1 aplican la rotación automática de claves antes de que se alcance el límite de uso recomendado.
