Missing Authorization in Kibana Leading to Unauthorized Deletion of Data
Missing Authorization (CWE-862) in Kibana can lead to unauthorized deletion of data via Exploiting Incorrectly Configured Access Control Security Levels (CAPEC-180). An authenticated user holding Synthetics privileges scoped to a single Kibana space could permanently delete Synthetics monitors that are shared into spaces they have no access to. Where a monitor is associated with a private location, the same operation also destroys the underlying Elastic Agent integration configuration without the authorization checks that Fleet would otherwise apply.
Affected Versions:

- All versions from 9.0.0 up to and including 9.4.6
- All versions from 9.5.0 up to and including 9.5.2
Affected Configurations:
Deployments where Kibana spaces are in use and Synthetics monitors are shared across more than one space. Deployments where monitors are not shared across spaces are not exposed to this vulnerability.
