CVE-2025-62593

Ray is vulnerable to RCE via Safari & Firefox Browsers through DNS Rebinding Attack

Published: Nov 26, 2025Updated: Dec 1, 2025 Sources: CVE List NVD GHSA BDUCWE-94

9.6CRITICAL

Description

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.
