In versions 2.53.0 and below, thedashboard HTTP server blocks browser-origin POST/PUT but does not cover DELETE, and key DELETE endpoints are unauthenticated by default. If the dashboard/agent is reachable (e.g., --dashboard-host=0.0.0.0), a web page via DNS rebinding or same-network access can issue DELETE requests that shut down Serve or delete jobs without user interaction. This is a drive-by availability impact. The fix for this vulnerability is to update to Ray 2.54.0 or higher.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H","score":6.5},"cwes":["CWE-396"],"references":["https://github.com/ray-project/ray/commit/0fda8b824cdc9dc6edd763bb28dfd7d1cc9b02a4","https://github.com/ray-project/ray/pull/60526","https://github.com/ray-project/ray/releases/tag/ray-2.54.0","https://github.com/ray-project/ray/security/advisories/GHSA-q5fh-2hc8-f6rq"],"products":["anyscale:ray"],"source":"nvd","synced_at":"2026-10-19T22:24:17.937441719+00:00"},"epss":{"cve":"CVE-2026-27482","score":0.00307,"percentile":0.23536,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-q5fh-2hc8-f6rq","url":"https://osv.dev/vulnerability/GHSA-q5fh-2hc8-f6rq","summary":"Ray dashboard DELETE endpoints allow unauthenticated browser-triggered DoS (Serve shutdown / job deletion)","modified":"2026-09-10T03:50:59.596811106Z","packages":[{"ecosystem":"PyPI","name":"ray","purl":"pkg:pypi/ray","ranges":["<2.54.0"],"fixed":["2.54.0"]}]},{"id":"PYSEC-2026-2271","url":"https://osv.dev/vulnerability/PYSEC-2026-2271","summary":"","modified":"2026-07-13T07:15:44.068322497Z","packages":[{"ecosystem":"PyPI","name":"ray","purl":"pkg:pypi/ray","ranges":["<2.54.0"],"fixed":["2.54.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
