### Summary In `[email protected]`, sandbox network hardening blocks `network=host` but still allows `network=container:<id>`. This can let a sandbox join another container's network namespace and reach services available in that namespace. ### Preconditions and Trust Model Context This issue requires a trusted-operator configuration path (for example setting `agents.defaults.sandbox.docker.network` in gateway config). It is not an unauthenticated remote exploit by itself. ### Details Current validation blocks only `host`, while forwarding other values to Docker create args: - `validateNetworkMode(network)` only rejects values in `BLOCKED_NETWORK_MODES = {"host"}`. - `buildSandboxCreateArgs(...)` validates then forwards `cfg.network` into `--network`. - Browser sandbox helper also treats `container:` as an accepted mode in network preparation. Effective behavior: - `host` -> blocked - `container:<id>` -> accepted and forwarded ### Impact Type: sandbox network isolation hardening bypass. Practical impact depends on deployment: - Requires ability to influence trusted sandbox network config. - Higher impact when a target container exposes privileged/internal network reachability. ### Remediation Block namespace-join style network modes (including `container:<id>`) for sandbox containers, and keep strict allowlisting for safe network modes. ### Patch Status Fixed on `main` in commit `14b6eea6e`: https://github.com/openclaw/openclaw/commit/14b6eea6e Follow-up refactor/cleanup (no policy rollback): https://github.com/openclaw/openclaw/commit/5552f9073 ### Publication Update (2026-02-25) `[email protected]` is published on npm and contains the fix commit(s) listed above.
