{"id":"CVE-2025-34351","aliases":["PYSEC-2026-518"],"url":"https://o3.security/vulnerability/CVE-2025-34351","summary":"Ray's New Token Authentication is Disabled By Default","details":"Anyscale Ray 2.52.0 contains an insecure default configuration in which token-based authentication for Ray management interfaces (including the dashboard and Jobs API) is disabled unless explicitly enabled by setting RAY_AUTH_MODE=token. In the default unauthenticated state, a remote attacker with network access to these interfaces can submit jobs and execute arbitrary code on the Ray cluster. NOTE: The vendor plans to enable token authentication by default in a future release. They recommend enabling token authentication to protect your cluster from unauthorized access.","published":"2025-11-27T03:30:26Z","modified":"2026-09-10T03:50:31.048877822Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"ray","fixedVersion":null}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/JLLeitschuh/security-research/security/advisories/GHSA-w8vc-465m-jjw6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-34351"},{"type":"WEB","url":"https://docs.ray.io/en/latest/ray-security/token-auth.html"},{"type":"PACKAGE","url":"https://github.com/ray-project/ray"},{"type":"WEB","url":"https://github.com/ray-project/ray/releases/tag/ray-2.52.0"},{"type":"WEB","url":"https://www.cve.org/resourcessupport/allresources/cnarules#section_4-1_Vulnerability_Determination"},{"type":"WEB","url":"https://www.linkedin.com/posts/jonathan-leitschuh_the-latest-piece-of-mind-bending-research-activity-7396976425997606912-qizE"},{"type":"WEB","url":"https://www.oligo.security/blog/shadowray-2-0-attackers-turn-ai-against-itself-in-global-campaign-that-hijacks-ai-into-self-propagating-botnet"},{"type":"WEB","url":"https://www.oligo.security/blog/shadowray-attack-ai-workloads-actively-exploited-in-the-wild"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/anyscale-ray-token-authentication-disabled-by-default-insecure-configuration"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:50:31.048877822Z"}}
