Summary
aodh, watcher vulnerability

Chen YuXiang discovered that OpenStack Aodh did not correctly enforce project scoping in its alarm list API and that the OpenStack Watcher webhook trigger endpoint did not apply authorization. An attacker could possibly use this issue to access sensitive alarm metadata or trigger unauthorized action plans.
