CVE-2023-48023
Published: 28 November 2023
Summary
CVE-2023-48023 is a critical-severity SSRF (CWE-918) vulnerability in Anyscale Ray. Its CVSS base score is 9.1 (Critical).
Operationally, ranked in the top 0.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2023-48023 is a server-side request forgery vulnerability (CWE-918) present in the /log_proxy endpoint of Anyscale Ray versions 2.6.3 and 2.8.0. The issue received a CVSS 3.1 score of 9.1, reflecting network attackability without authentication or user interaction and resulting in high confidentiality and integrity impact.
An unauthenticated remote attacker can exploit the flaw to perform SSRF against internal resources reachable by the Ray instance. Successful abuse allows the attacker to read or interact with otherwise inaccessible services, though the vendor states that Ray is intended solely for strictly controlled network environments and therefore considers external exposure outside its documented threat model.
Vendor documentation at docs.ray.io emphasizes deployment only inside trusted networks and does not describe a software patch or configuration workaround for the reported endpoint. Public references, including Bishopfox analysis, document the SSRF vector but align with the vendor position that the software should never be reachable from untrusted networks.
The associated EPSS score sits at 0.8919 with no indicated rise from a lower baseline.
