DescriptionNVD

Ray is an AI compute engine. In versions 2.53.0 and below, thedashboard HTTP server blocks browser-origin POST/PUT but does not cover DELETE, and key DELETE endpoints are unauthenticated by default. If the dashboard/agent is reachable (e.g., --dashboard-host=0.0.0.0), a web page via DNS rebinding or same-network access can issue DELETE requests that shut down Serve or delete jobs without user interaction. This is a drive-by availability impact. The fix for this vulnerability is to update to Ray 2.54.0 or higher.

AnalysisAI

Ray dashboard versions 2.53.0 and below lack proper authentication on DELETE endpoints, allowing unauthenticated attackers to terminate Serve instances or remove jobs through DNS rebinding or same-network attacks. Public exploit code exists for this vulnerability, which impacts Ray deployments with dashboards exposed to network access. …
