CVE-2026-72630 is a high-severity vulnerability in Kibana Fleet involving incorrect authorization that allows privilege escalation. The flaw occurs because Fleet restricts management of integration policies to specific integrations, but when updating an existing policy, the authorization check is performed against the stored integration rather than the new integration supplied. This enables an authenticated user with Elastic Defend endpoint policy management privileges to convert an endpoint policy they control into a policy for a different integration and supply that integration's configuration.

Incorrect Authorization (CWE-863) in Kibana Fleet can lead to privilege escalation via Privilege Abuse (CAPEC-122). Fleet restricts some callers to managing integration policies for one specific integration. When an existing integration policy was updated, that restriction was evaluated against the integration recorded on the stored policy rather than against the replacement integration supplied with the update. An authenticated user holding only the Elastic Defend endpoint policy management privilege was therefore able to convert an endpoint policy they administer into a policy for a different integration, and to supply that integration's configuration at the same time.
