CVE-2025-37732Network attack vector

Authenticated HTML rendering via integration package upload bypass

Published Dec 15, 2025 · Updated Dec 15, 2025

Cross-site scripting in affected Elastic Kibana releases allows remote authenticated users to render HTML in another user's browser via package upload. The integration package upload path allows package-supplied content to bypass the prior neutralization fix and be rendered as an HTML page. Exploitation requires a role with All permissions under Management for Fleet and Integrations plus interaction by the user whose browser renders the injected content.
