Unauthenticated Superuser Token Issuance via Auto-Login Endpoint
IBM Langflow OSS 1.0.0 through 1.10.0 could allow a remote attacker to gain unauthorized access due to improper authentication in the /api/v1/login/auto_login endpoint. The endpoint issues long-lived superuser bearer tokens without requiring authentication when the AUTO_LOGIN configuration is enabled (enabled by default), which may allow an unauthenticated network attacker to obtain full administrative access. Additionally, permissive cross-origin resource sharing (CORS) settings may allow tokens to be exposed to unintended origins, increasing the risk of unauthorized access.
