What happened and what to do
The Ubuntu Security advisory, published on October 5, 2026, describes two authorization flaws in OpenStack. Aodh did not correctly apply project scope to its alarm-listing API, potentially exposing confidential metadata. In Watcher, a webhook trigger endpoint did not enforce authorization, potentially allowing action plans to be triggered without permission.
A company operating these services can inventory versions and exposed endpoints, review project scopes and authorization controls, and inspect records of calls and triggers. It can also implement monitoring for out-of-scope access and alerts for action-plan executions, while updating incident response procedures.
