--- security: - | `OSSA-2017-005`_: Nova Filter Scheduler bypass through rebuild action By rebuilding an instance, an authenticated user may be able to circumvent the FilterScheduler bypassing imposed filters (for example, the ImagePropertiesFilter or the IsolatedHostsFilter). All setups using the FilterScheduler (or CachingScheduler) are affected. The fix is in the `nova-api` and `nova-conductor` services. .. _OSSA-2017-005: https://security.openstack.org/ossa/OSSA-2017-005.html
