OpenStack Manila: critical vulnerability

OpenStack Manila

In OpenStack Manila before 23.0.1, multiple Manila API operations on public shares do not verify that the caller owns the share. The API controllers authorize operations against the caller's own project context, then load a foreign public share without re-authorizing against the share's actual owner.

Do this now

Upgrade OpenStack Manila to 23.0.1, 22.0.2, or 21.0.3, or apply the matching fix listed in Fix it (+1 more lines in Fix it).
