Affected products & platforms
Description
Outgoing remote migrations were previously allowed with just VM.Migrate on the source side. While a regular, intra-cluster migration does not, a remote migration effectively gives access to the guest's configuration, and potentially allows removing the guest on the source side.
Corresponding additional privilege checks were added. This issue was reported privately by Project Loupe, and additionally by Vítor Fonte.
Packages: qemu-server, pve-container.
Affected product named by the advisory: Proxmox Virtual Environment.
