CVE-2023-48022 is a critical-severity (CVSS 9.8) Server-Side Request Forgery (SSRF) vulnerability in ray. 4 public exploit or proof-of-concept references are indexed, so weaponization risk is real. The records list no fixed version yet; check the vendor advisory below and apply the mitigations in the meantime.
Ray has arbitrary code execution via jobs submission API
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

Real-World Exposure
rayReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
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.)

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ray, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of ray for CVE-2023-48022. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.
How to detect CVE-2023-48022
A community-maintained Nuclei template exists for this CVE. You can scan for it directly:
nuclei -id cve-2023-48022 -u https://target- Template
- Anyscale Ray - Remote Code Execution
- Severity
- critical
- Impact
- Unauthenticated attackers with network access to the Ray Dashboard API can execute arbitrary code remotely as root, leading to complete system compromise.
- Remediation
- Upgrade Anyscale Ray to version 2.6.4 or later, or version 2.8.1 or later, and restrict network access to the Ray Dashboard API.

Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
