medium Tenable Self-Hosted Container Security Plugin ID 457887

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-27482)

Solution

Update the ray library and its related packages to version 2.52.0+echo.1 or later.
