The external_oauth2_token middleware fails to sanitize incoming authentication headers before processing OAuth 2.0 tokens. By sending forged identity headers such as X-Is-Admin-Project, X-Roles, or X-User-Id, an authenticated attacker may escalate privileges or impersonate other users. All deployments using the external_oauth2_token middleware are affected."},{"lang":"es","value":"Se descubrió un problema en OpenStack keystonemiddleware 10.5 hasta 10.7 antes de 10.7.2, 10.8 y 10.9 antes de 10.9.1, y 10.10 hasta 10.12 antes de 10.12.1. El middleware external_oauth2_token no sanea los encabezados de autenticación entrantes antes de procesar los tokens de OAuth 2.0.
