Docker Sandboxes can silently republish a sandbox service after an operator removes its automatically assigned host-port mapping. The daemon removes the active binding but retains the original publication request, allowing a later port change or sandbox restart to publish the service again on a new host port. An attacker able to reach the restored endpoint may regain access to the service. Both TCP and UDP mappings are affected. Exposure is limited to the original bind address, which defaults to loopback. The issue is fixed in version 0.53.0.
