Anything that is not `bridge` runs isolated: `host` and unknown network modes are downgraded to `none` at container start, with a warning on stderr. +**Security note:** `bridge` is not isolated from the host. A bridge container reaches the Docker gateway and services bound on the host's network interfaces, and on cloud machines the instance metadata endpoint (IMDS, `169.254.169.254`) and your LAN. Use `none` (or an `Internal` network) when that matters. Because a wider network is a privilege, `bridge` and attached networks must be explicit operator choices: a project-level `./odek.json` that requests them triggers the sandbox-override approval prompt above. The prompt shows each network's name, full ID, `Internal` flag and Compose project, and the ID is part of the approval key, so a recreated network asks again. + +An invalid value (`host`, `container:x`, an unknown name) is a configuration error, not a reason to run unsandboxed. `ODEK_SANDBOX_NETWORK_LENIENT=1` restores the older behaviour of downgrading an invalid mode to `none` with a warning. + +**Attached networks.** Names must match `^[A-Za-z0-9][A-Za-z0-9_.-]{0,127}$` and may not be `host`, `none`, `bridge` or `default`; at most 8 are attached. Each is inspected: only local bridge networks are accepted and the full network ID is what Docker receives. The first network is given to `docker run`, the rest are connected after start; any failure removes the container, and teardown never removes networks. A warning is printed when a network is not `Internal` or is combined with `bridge`. `--sandbox-compose ` finds the project's networks by label (never by guessing `_default`) and fails with a hint when none exist. + +**What the model is told.** The system prompt (and the `shell` tool description) ends with an execution-environment block: container, `/workspace`, user, network mode, attached networks, service DNS names of containers already on them (charset-checked, at most 20) and that `localhost` is the container itself. Batch approval cards show the active networks. Sub-agents only narrow: a child keeps a subset of the networks its parent resolved and never re-resolves a Compose project. ## File injection diff --git a/docs/SECURITY.md b/docs/SECURITY.md index 234027b9..b594e0b4 100644 --- a/docs/SECURITY.md +++ b/docs/SECURITY.md @@ -32,7 +32,7 @@ Unsandboxed runs print a one-time stderr warning that the agent has full host ac - No filesystem access beyond the working directory (mounted read-only when configured). - `write_file`, `patch` do not touch the host filesystem when `--sandbox` is active; they translate the host path to `/workspace/...` and copy content into the running container with `docker cp`.

Project-requested networks are shown with their full ID, `Internal` flag and Compose project, the approval key binds those IDs, and `setupSandbox` checks the networks it resolves again at container creation against the approved IDs: a network that joined the Compose project, or was recreated under an approved name, after the prompt is refused with a configuration error. **Execution budgets use a clamp merge.** The `limits` config section (`internal/budget` + `clampProjectLimits` in `internal/config/loader.go`) uses a clamp instead of the usual overlay: the global `~/.odek/config.json` may set any execution budget, but the untrusted project `./odek.json` may only *lower* one — raise attempts are clamped to the global value with a stderr warning, and zeroing/omitting a field re-inherits the global limit — so a checked-in config can never disable the operator's runtime/token/cost caps. Project-set per-million prices are rejected outright because a lower price would silently weaken cost enforcement. CLI flags are layer-4 operator intent and may set limits explicitly in either direction. Enforcement is fail-stop: on exhaustion the loop emits `budget_exceeded`, persists the latest safe session state, and returns a typed `budget.Error` (CLI exit code 4).

A broken configuration is never "Docker unavailable": an invalid network value, an unresolvable network, or any image, limit, user or `docker run` failure while the Docker daemon answers stops the run with a configuration error, explicit or not; only an unreachable daemon takes the fallback. **Implicit `Dockerfile.odek` builds are approval-gated.** A `Dockerfile.odek` in the working directory is repo-controlled, and `docker build` executes its `RUN` instructions outside the sandbox threat model (default capabilities, entire working directory readable as build context). The implicit build is therefore gated like project sandbox overrides: an interactive TTY prompt at startup (`y` = once, `t` = trust this project), persisted approvals in `~/.odek/project_sandbox_approvals.json`, or `ODEK_APPROVE_PROJECT_SANDBOX=1` for CI. Non-TTY runs without approval fail closed. The approval key includes the **Dockerfile content hash**, so editing the file invalidates a prior trust and forces re-review, and `setupSandbox` re-verifies approval immediately before building — closing the window where a Dockerfile appears or changes after startup (e.g. a serve-mode sandbox created per WebSocket connection). Builds run with `--network=none` by default, so `RUN` steps cannot fetch payloads or exfiltrate build-context data; `ODEK_SANDBOX_BUILD_NETWORK=1` (operator-only) opts back into networked builds for legitimate package installs.

Only an unreachable daemon, or an image that is not cached and cannot be pulled (offline machine, registry outage, unknown tag), takes the fallback; the image is pulled before `docker run`, so a run failure with the image present comes from the configuration. **Implicit `Dockerfile.odek` builds are approval-gated.** A `Dockerfile.odek` in the working directory is repo-controlled, and `docker build` executes its `RUN` instructions outside the sandbox threat model (default capabilities, entire working directory readable as build context). The implicit build is therefore gated like project sandbox overrides: an interactive TTY prompt at startup (`y` = once, `t` = trust this project), persisted approvals in `~/.odek/project_sandbox_approvals.json`, or `ODEK_APPROVE_PROJECT_SANDBOX=1` for CI. Non-TTY runs without approval fail closed. The approval key includes the **Dockerfile content hash**, so editing the file invalidates a prior trust and forces re-review, and `setupSandbox` re-verifies approval immediately before building — closing the window where a Dockerfile appears or changes after startup (e.g. a serve-mode sandbox created per WebSocket connection). Builds run with `--network=none` by default, so `RUN` steps cannot fetch payloads or exfiltrate build-context data; `ODEK_SANDBOX_BUILD_NETWORK=1` (operator-only) opts back into networked builds for legitimate package installs. diff --git a/internal/sandbox/networks.go b/internal/sandbox/networks.go index 217e5bdb..2ef9e730 100644 --- a/internal/sandbox/networks.go +++ b/internal/sandbox/networks.go @@ -171,7 +171,7 @@ func serviceNames(ctx context.Context, network string, containers map[string]str own := containers[cid].Name found := false for _, a := range aliases[cid] { - if a == own || shortContainerIDRE.MatchString(a) || strings.HasPrefix(cid, a) { + if a == own || shortContainerIDRE.MatchString(a) || (len(a) >= 12 && strings.HasPrefix(cid, a)) { continue } add(a) diff --git a/internal/sandbox/red_service_alias_test.go b/internal/sandbox/red_service_alias_test.go index 75b096d2..a9a63cdf 100644 --- a/internal/sandbox/red_service_alias_test.go +++ b/internal/sandbox/red_service_alias_test.go @@ -61,3 +61,27 @@ func TestRED_ResolveNetworks_ServiceNamesFallBackToContainerNames(t *testing.T) t.Errorf("ServiceNames = %q, want the container names as a fallback", got) } } + +// A short service name that happens to be a hex prefix of the container ID +// ("db", "cafe") is still a service name; only short-ID aliases are dropped. +func TestRED_ServiceNames_KeepsHexLookingServiceNames(t *testing.T) { + cid := "db" + strings.Repeat("0", 62) + f := &netFakeDocker{handler: func(args []string) ([]byte, error) { + switch { + case isNetInspect(args): + return fmt.Appendf(nil, `[{"Name":"app","Id":%q,"Driver":"bridge","Scope":"local","Internal":true,"Labels":{}, + "Containers":{%q:{"Name":"app-db-1"}}}]`, id('a'), cid), nil + case len(args) >= 2 && args[0] == "inspect": + return fmt.Appendf(nil, `[{"Id":%q,"NetworkSettings":{"Networks":{"app":{"Aliases":["app-db-1","db",%q]}}}}]`, cid, cid[:12]), nil + } + return nil, errors.New("unexpected docker call") + }} + f.install(t) + nets, err := ResolveNetworks(context.Background(), []string{"app"}) + if err != nil { + t.Fatal(err) + } + if got := strings.Join(nets[0].ServiceNames, ","); got != "db" { + t.Errorf("ServiceNames = %q, want db", got) + } +} From c7f83a4ae3bdd57c990c342e18f907ef5546d4b6 Mon Sep 17 00:00:00 2001 From: Rolando Santamaria Maso <4096860+jkyberneees@users.noreply.github.com> Date: Sun, 25 Oct 2026 13:14:55 +0100 Subject: [PATCH 22/22] fix(sandbox): wrap Docker-reported names as external data without an ingest The engine-label wrapper is reserved for engine-injected context. Use the external-content wrapper (with the guard scan) and record no ingest, so listing network and service names never taints the session.
