Prior to version 2.52.0, developers working with Ray as a development tool can be exploited via a critical RCE vulnerability exploitable via Firefox and Safari. This vulnerability is due to an insufficient guard against browser-based attacks, as the current defense uses the User-Agent header starting with the string \"Mozilla\" as a defense mechanism. This defense is insufficient as the fetch specification allows the User-Agent header to be modified. Combined with a DNS rebinding attack against the browser, and this vulnerability is exploitable against a developer running Ray who inadvertently visits a malicious website, or is served a malicious advertisement (malvertising). This issue has been patched in version 2.52.0.","cvss_version":"3.1","cvss_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","base_score":8.8,"base_severity":"HIGH","attack_vector":"NETWORK","privileges_req":"NONE","user_interaction":"REQUIRED","scope":"UNCHANGED","impact_c":"HIGH","impact_i":"HIGH","impact_a":"HIGH","cwe_ids":["CWE-94","CWE-352"],"in_kev":true,"kev_date_added":"2026-08-17","kev_ransomware":false,"epss_score":0.6015,"epss_percentile":0.99136,"cap_rule_version":"0.1.1","stage":"INITIAL_ACCESS","req_access":"NONE","req_vector":"NETWORK","req_user_interaction":true,"grant_access":"USER","caps":["CODE_EXEC","TAMPER"],"terminal":false,"cap_confidence":"high","ingested_at":"2026-10-28T03:24:50.302798+00:00","first_seen":"2025-11-26T23:15:47.927000+00:00","kev_first_seen":"2026-08-17T00:00:00+00:00","novelty_score":0.0,"novelty_reasons":[],"novelty_at":"2026-10-09T03:25:14.214996+00:00","vendors":["anyscale"],"products":["ray"],"affected":[{"vendor":"anyscale","product":"ray","ranges":["< 2.52.0"]}]}
