Dozzle is a realtime log viewer for docker containers. Prior to version 9.0.3, a flaw in Dozzle’s agent-backed shell endpoints allows a user restricted by label filters (for example, `label=env=dev`) to obtain an interactive root shell in out‑of‑scope containers (for example, `env=prod`) on the same agent host by directly targeting their container IDs. Version 9.0.3 contains a patch for the issue.

CVE-2026-24740 [HIGH] CWE-284 Dozzle Agent Label-Based Access Control Bypass Allows Unauthorized Container Shell Access
Dozzle Agent Label-Based Access Control Bypass Allows Unauthorized Container Shell Access
### Summary
A flaw in Dozzle’s agent-backed shell endpoints allows a user restricted by label filters (for example, `label=env=dev`) to obtain an interactive root shell in out‑of‑scope containers (for example, `env=prod`) on the same agent host by directly targeting their container IDs.
**Note**: Tested on `v9.0.2` likely affects all versions with agent mode support.
### Details
When SIMPLE auth is enabled, Dozzle supports per‑user label filters in `users.yaml` (for example, filter: `label=env=dev`) to restrict which containers a user can see and interact with. These filters are propagated into the shell handlers, which resolve the target container via `h.hostService.FindContainer(hostKey(r), id, u
