CVE-2025-37728Network attack vector

Cross-space credential exposure via shared connector cache

Published Oct 7, 2025 · Updated Oct 7, 2025

Credential exposure in the CrowdStrike connector in Elastic Kibana allows remote authenticated users to obtain credentials across spaces. The connector retrieves cached authentication data without keeping the cache scoped to its Kibana space, so running a connector can return credentials stored for another space. Exploitation requires connector privileges in one space and an instance configured to use the CrowdStrike connector; the exposed credentials can access the linked CrowdStrike service.
