The fix for this CVE was reverted in USN-6073-6 to USN-6073-9 as it was causing problems detaching volumes. These updates may require configuration changes, see: https://discourse.ubuntu.com/t/cve-2023-2088-for-charmed-openstack/37051 https://lists.openstack.org/pipermail/openstack-discuss/2023-July/034439.html Due to the extensive changes required to fix this issue, we will not be releasing updates for Focal and earlier.
