What happened and what to do
Notice USN-8870-1, published on October 5, 2026, reports that OpenStack Aodh did not correctly enforce project scope in its alarm-listing API. It also says that the OpenStack Watcher webhook trigger endpoint did not enforce authorization. According to the notice, these issues could allow access to confidential alarm metadata or the triggering of unauthorized action plans. The reference is notice USN-8870-1 in the Ubuntu Security portal; consult the original by its identifier to verify details and any updates.
A practical response is to review project scopes, access controls, and webhook endpoint exposure in the OpenStack services in use. A company can also log and monitor API calls and trigger attempts, set alerts for unusual operations, and test whether permissions restrict each action to the authorized project.
