## Overview

A path traversal vulnerability was identified in Ray Dashboard (default port 8265) in Ray versions prior to 2.8.1. Due to improper validation and sanitization of user-supplied paths in the static file handling mechanism, an attacker can use traversal sequences (e.g., ../) to access files outside the intended static directory, resulting in local file disclosure.

## Affected

- `ray < 2.8.1`

## Remediation

Upgrade past the affected range:

- `ray 2.8.1`
