Published May 17, 2021 · Updated Sep 16, 2024

Missing authentication in IBM Planning Analytics Local 2.0 allows remote attackers to read and modify data through its Redis service. The Planning Analytics Workspace component connects to a Redis server that accepts network requests without enforcing password authentication. No account or user interaction is required; exploitation depends on network reachability to Redis and permits unauthorized server access.
