FKIE_CVE-2025-62593
Vulnerability from fkie_nvd - Published: 2025-11-26 23:15 - Updated: 2026-10-19 13:10
Severity
Summary
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.

"value": "Ray es un motor de c\u00f3mputo de IA. Versiones anteriores a la versi\u00f3n 2.52.0, los desarrolladores que trabajan con Ray como herramienta de desarrollo pueden ser explotados a trav\u00e9s de una cr\u00edtica vulnerabilidad RCE explotable a trav\u00e9s de Firefox y Safari. Esta vulnerabilidad se debe a una protecci\u00f3n insuficiente contra ataques basados en navegador, ya que la defensa actual utiliza el encabezado User-Agent que comienza con la cadena \u201cMozilla\u201d como mecanismo de defensa. Esta defensa es insuficiente ya que la especificaci\u00f3n fetch permite que el encabezado User-Agent sea modificado. Combinado con un ataque de reencuadernaci\u00f3n de DNS contra el navegador, esta vulnerabilidad es explotable contra un desarrollador que ejecuta Ray que visita inadvertidamente un sitio web malicioso, o se le sirve un anuncio malicioso (publicidad maliciosa). Este problema ha sido parcheado en la versi\u00f3n 2.52.0."
