CVE-2024-37287Network attack vector

Authenticated code execution via prototype pollution

Published Aug 13, 2024 · Updated Aug 13, 2024

Prototype pollution in Elastic Kibana 7.7.0 through 7.17.22 and 8.0.0 through 8.14.1 allows remote authenticated users to execute arbitrary code. Crafted content written to .ml-anomalies* triggers prototype pollution in an undisclosed Kibana code path that ultimately reaches code execution. Exploitation requires ML and connector access plus non-default write access to internal ML indices; containerized execution remains confined to the Kibana container where the documented sandbox controls apply.
