Detailsinfo

A vulnerability classified as problematic was found in ray-project ray up to 2.53.x. This vulnerability affects an unknown code of the component DELETE Endpoint. The manipulation with an unknown input leads to a generic exception vulnerability. The CWE definition for the vulnerability is CWE-396. Catching overly broad exceptions promotes complex error handling code that is more likely to contain security vulnerabilities. As an impact it is known to affect integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability was named CVE-2026-27482 since 02/19/2026. The exploitation appears to be difficult. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. The technical details are unknown and an exploit is not available.
