What is CVE-2026-27482?

The Ray AI Compute Engine, in versions up to 2.53.0, exhibits a vulnerability where the dashboard HTTP server allows unauthenticated DELETE requests. This occurs because the DELETE endpoints are not sufficiently secured, creating the risk of malicious actors issuing commands that could terminate services or delete jobs without user consent. To mitigate this, users are strongly advised to update to version 2.54.0 or later, which addresses this security concern.
