CVE-2026-27482: Anyscale Ray

Medium severity, CVSS 6.5. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Anyscale Ray: before 2.54.0 (fixed in 2.54.0)
