CVE-2020-27781 (https://bugzilla.redhat.com/show_bug.cgi?id=1900109):

User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila, resulting in potential privilege escalation. An Open Stack Manila user can request access to a share to an arbitrary cephx user, including existing users. The access key is retrieved via the interface drivers. Then, all users of the requesting OpenStack project can view the access key. This enables the attacker to target any resource that the user has access to. This can be done to even "admin" users, compromising the ceph administrator. This flaw affects Ceph versions prior to 16.2.0.


Contrary to the CVE text this was also fixed in 15.2.8 and 14.2.16 (I will
request an update for it):
