NVD description
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.
What to do
- Upgrade Ray to
2.8.1or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
