Executive Summary

CVE-2026-55814 is a missing authentication vulnerability in Apache Ranger versions up to 2.8.0. It affects Download APIs, allowing unauthorized access to plugin data without requiring authentication.

Detection Guidance

Check Apache Ranger version with: curl -s http://<ranger-server>:6080/service/version | grep version. If version <= 2.8.0, the system is vulnerable. Inspect network traffic for unauthenticated requests to /service/plugins/download or similar endpoints.
