Synopsis

H2O Flow Unauthenticated Access

Description

H2O Flow is an open-source user interface for H2O, an open-source, distributed and scalable machine learning and predictive analytics platform. By default, H2O Flow does not require authentication to access the application. This allows an attacker to access sensitive data. This detection is included in the AI and LLM category.

Solution

Authentication should be enforced to prevent unauthorized access to the H2O Flow interface.
