Impact

CVSS 9.8, EPSS 92.2%, PoC available. Thousands of Ray clusters have been found exposed on the internet. The ShadowRay campaign (2024) compromised production AI/ML environments to steal model weights, training data, and cloud credentials. The 'disputed' status causes many organizations to deprioritize patching.

Exploit ScenarioDerived

An attacker scans for exposed Ray dashboards on port 8265. Finding an unprotected cluster, they submit a job via the REST API that exfiltrates AWS credentials from the instance metadata service, steals ML model weights from the shared object store, and deploys a cryptominer across all worker nodes.

Emergency Immediate action required. Why: CRITICAL + EPSS > 30%, no patch available.
No patch listed yet 92.2% exploitation probability (EPSS)

AnalysisAIv1 – Mar 26, 2026

Anyscale Ray 2.6.3 and 2.8.0 expose an unauthenticated job submission API that allows remote code execution by design. The vendor considers this expected behavior for a compute framework intended for trusted network environments, but internet-exposed Ray clusters are actively exploited by cryptominers and data exfiltration campaigns.

Earlier versions of this analysis (1)
v1 Mar 26, 2026 - 11:19 CVSS 9.8

Ray's unauthenticated job submission API enables RCE by design, creating critical risk when clusters are inadvertently exposed to the internet.

RemediationAI

Never expose Ray clusters to the internet. Place Ray behind a VPN or private network with strict access controls. Enable Ray's authentication features if available in newer versions. Monitor Ray job submission logs for unexpected workloads. Audit cloud security groups for port 8265 exposure.

Technical ContextAI · show details

Ray is a distributed computing framework for ML/AI workloads. The dashboard (port 8265) and job submission API intentionally allow unauthenticated code execution as this is the framework's core functionality. The vendor explicitly states Ray is not designed for untrusted network exposure. However, cloud misconfigurations frequently expose Ray clusters to the internet, and the API accepts arbitrary Python code execution.

CRITICAL 9.8

DescriptionCVE.org

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.)

Executive ViewAI

Why It Matters

Organizations using Anyscale Ray 2.6.3 and 2.8.0 face critical risk from CVE-2023-48022, a server-side request forgery vulnerability rated CVSS 9.8. Attackers could trick authenticated users into performing unintended actions, potentially modifying critical settings or data. With an EPSS score of 92%, this vulnerability faces very high likelihood of exploitation. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.

Business Impact: Severe
Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Implement strict egress filtering; (2) Use allowlists for outbound connections; (3) Block access to cloud metadata endpoints.
