# CVE-2023-48022: Ray has arbitrary code execution via jobs submission API

**Signal:** High exploit likelihood. EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 83.9% , percentile 99.7: FIRST’s model estimates a 83.9% chance of exploitation activity in the next 30 days, higher than 99.7% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes ray (PyPI) <= 2.49.2, no fixed version listed . Check your lockfile, including transitive dependencies.
- Editorial verdict: Check exposure. ShadowRay: Exposed Ray Clusters Hijacked (CVE-2023-48022) — There is no patch to install: if any Ray dashboard, Jobs or Client port is reachable from an untrusted network, anyone who can reach it can run code on your cluster.

## What it is

Anyscale Ray 2.6.3 and 2.8.0 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. (Also, within that environment, customers at version 2.52.0 and later can choose to use token authentication.)

## Affected packages

- PyPI `ray` <= 2.49.2 → fixed: none listed

## Affected products (CVE record)

- n/a n/a: see advisory

## Severity

- CISA-ADP CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.8 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 83.94% probability of exploitation activity in the next 30 days; percentile 99.7.
