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.","published_at":"2026-02-21T09:18:26.027000Z","last_modified_at":null,"cvss_v3_score":5.9,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:H","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"poc","ssvc_automatable":false,"ssvc_technical_impact":"partial","cwes":["CWE-396"],"nvd_references":["https://github.com/ray-project/ray/security/advisories/GHSA-q5fh-2hc8-f6rq","https://github.com/ray-project/ray/pull/60526","https://github.com/ray-project/ray/commit/0fda8b824cdc9dc6edd763bb28dfd7d1cc9b02a4","https://github.com/ray-project/ray/releases/tag/ray-2.54.0"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T23:46:59.033383Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"H","value_label":"High"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"ray-project","vendor_name":"ray-project","product_slug":"ray","product_name":"ray","version_start":"< 2.54.0","version_start_inclusive":true,"version_end":"< 2.54.0","version_end_inclusive":true,"cpe23_uri":"cve5:ray-project:ray:< 2.54.0:< 2.54.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/ray-project/ray/security/advisories/GHSA-q5fh-2hc8-f6rq","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/ray-project/ray/pull/60526","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/ray-project/ray/commit/0fda8b824cdc9dc6edd763bb28dfd7d1cc9b02a4","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/ray-project/ray/releases/tag/ray-2.54.0","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-02-21T09:18:26.027000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:52:22.671512Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:22.671512Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:22.671512Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T23:46:59.033383Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T23:46:59.033383Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T23:46:59.033383Z","label":"SSVC decision revised","source":"vulnrichment"}]}
