GHSA-pxxv-rv32-2qgv · Severity: medium · Ecosystem: pip — OpenStack Nova uses insecure keystone middleware tmpdir by default
keystone/middleware/auth_token.py in OpenStack Nova Folsom, Grizzly, and Havana uses an insecure temporary directory for storing signing certificates, which allows local users to spoof servers by pre-creating this directory, which is reused by Nova, as demonstrated using /tmp/keystone-signing-nova on Fedora.
