Overview

What is CVE-2026-72649?

Deserialization of Untrusted Data (CWE-502) in the Elasticsearch machine learning component can lead to remote code execution via Object Injection (CAPEC-586). A specially crafted trained model artifact could cause attacker-controlled logic to execute with a materially broader system-call surface than intended.

Exploitation requires an authenticated user with sufficient privileges to create and deploy trained models.
