Is this vulnerability remotely exploitable?

Yes. Any user who can remotely reach the Dozzle interface or API, and who is granted shell access constrained by label filters, may exploit this issue by targeting container IDs directly, assuming network access to the Dozzle agent is available.

What level of access does an attacker need to exploit this?

The attacker needs logical access to Dozzle with permissions that allow shell sessions into some containers (for example, dev containers restricted by labels). No direct host-level access is required, but the ability to initiate a shell via Dozzle is necessary.

What is the safest general fix pattern?

Implement strict, centralized authorization for shell endpoints that validates the requested container against the user's allowed scope using label filters, roles, and environment policies. Ensure that backend authorization does not rely on UI-based filtering and that every shell creation path passes through the same access-control logic.
