# CVE-2023-48022: CVE-2023-48022

- Exploited (CISA KEV): no
- Published: 2023-11-28
- CVSS: 9.8 CRITICAL (v3.1)
- EPSS: 83.9% (100th percentile)

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.)

"No public claim" means no vendor statement names this CVE; "Before feed history" means the CVE is older than the vendor feed. In both cases generic rules may still block it.
