Doc Text:	A flaw was found in Ray’s HTTP API endpoint handling (e.g. /api/jobs, /api/job_agent/jobs/), which allows a remote attacker to trigger arbitrary code execution when a developer using Ray visits a malicious website in a vulnerable browser (e.g. Firefox or Safari). The root cause is an insufficient defense relying solely on the User-Agent header starting with “Mozilla”, which can be manipulated under the fetch specification — enabling a DNS-rebinding attack to bypass browser-based protections.

Description OSIDB Bzimport 2025-11-26 23:01:49 UTC

Ray is an AI compute engine. 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.
