## What is CVE-2026-72662?

CVE-2026-72662 is a medium-severity missing authorization vulnerability in Elastic Kibana, published on 26 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to unauthorized disclosure, modification, and deletion of data via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user granted the Timeline feature privilege in a Kibana space could enumerate, read, modify, and delete draft Timeline objects belonging to other users in the same space. Read access is sufficient for enumeration and disclosure; the Timeline write privilege is required for modification and deletion.

Weakness: CWE-639 (Authorization Bypass Through User-Controlled Key)
