Published: 10 May 2023

A flaw was found in OpenStack due to an inconsistency between Cinder and Nova. This issue can be triggered intentionally or by accident. A remote, authenticated attacker could exploit this vulnerability by detaching one of their volumes from Cinder. The highest impact is to confidentiality.

The fix for this CVE was reverted in USN-6073-6 to USN-6073-9
