CVE-2025-62593

Critical
Published: Translated: NVD NIST

Summary

Ray is an AI compute engine. Prior to version 2.52.0, developers using Ray as a development tool can be exploited via a critical RCE vulnerability exploitable via Firefox and Safari. This is due to insufficient guard against browser-based attacks, as the current defense uses the User-Agent header starting with 'Mozilla'. This defense is insufficient because the fetch specification allows modifying the User-Agent header. Combined with DNS rebinding, the vulnerability is exploitable against a developer who inadvertently visits a malicious website or sees a malicious ad. Patched in version 2.52.0.

Risk Assessment

A developer using Ray could be attacked by a malicious website, leading to remote code execution on their machine and compromising the development environment.

Recommendation

Update Ray to version 2.52.0 or later. Educate developers about the risk of visiting unknown websites while using Ray.

Original NVD description (English source)

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.
