PYSEC-2026-858
OpenStack Nova Router metadata queries are not restricted by tenant
Quick fix
PYSEC-2026-858 — nova: upgrade to the fixed version with the command below.
pip install --upgrade 'nova>=12.0.0a0'Details
Interaction error in OpenStack Nova and Neutron before Havana 2013.2.1 and icehouse-1 does not validate the instance ID of the tenant making a request, which allows remote tenants to obtain sensitive metadata by spoofing the device ID that is bound to a port, which is not properly handled by (1) api/metadata/handler.py in Nova and (2) the neutron-metadata-agent (`agent/metadata/agent.py`) in Neutron.
