CVE-2020-10736
Published: 22 June 2020
An authorization bypass vulnerability was found in Ceph versions 15.2.0 before 15.2.2, where the ceph-mon and ceph-mgr daemons do not properly restrict access, resulting in gaining access to unauthorized resources. This flaw allows an authenticated client to modify the configuration and possibly conduct further attacks.
