## Overview

Anyscale Ray allows a remote attacker to execute arbitrary code via the job submission API. NOTE: the vendor's position is that this report is irrelevant because Ray, as stated in its documentation, is not intended for use outside of a strictly controlled network environment.

## Affected packages

- `ray <= 2.49.2`

## Remediation

Refer to the advisory for the patched release.
