CVE-2025-68384Network attack vector

Authenticated node crash via oversized profile updates

Published Dec 18, 2025 · Updated Dec 18, 2025

Resource exhaustion in Elastic Elasticsearch allows remote authenticated users to crash nodes by submitting oversized user profile data. ProfileService.updateProfileData merged attacker-controlled labels and application data into stored profiles without enforcing a size limit. Low-privileged access is sufficient, and repeated oversized updates can exhaust heap memory and cause a persistent out-of-memory crash.
