https://notcve.org/view.php?id=CVE-2023-3637
25 Jul 2023 — An uncontrolled resource consumption flaw was found in openstack-neutron. This flaw allows a remote authenticated user to query a list of security groups for an invalid project. This issue creates resources that are unconstrained by the user's quota. If a malicious user were to submit a significant number of requests, this could lead to a denial of service. OpenStack Networking is a virtual network service for OpenStack. • https://access.redhat.com/errata/RHSA-2023:4283 • CWE-400: Uncontrolled Resource Consumption •
