From 2d53392f24e523fe08f384645fe142036c9da035 Mon Sep 17 00:00:00 2001 From: oratis Date: Thu, 28 May 2026 13:17:31 +0800 Subject: [PATCH] =?UTF-8?q?test(core,docs):=20M3.5=20=E2=80=94=20sandbox?= =?UTF-8?q?=20attack-vector=20test=20suite=20+=20security-model.md?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes the "M3.5: 75% — missing attack vectors" gap from the morning report. · packages/core/src/sandbox/attacks.test.ts (17 tests) - 6 SBPL hostile-input tests: paren/quote/backslash escaping, deny-after-allow ordering, no implicit network when allowedDomains=[], no implicit writes to /usr|/System|/Library. - 3 bwrap arg safety tests: no --share-net, only cwd is bare --bind, pid/ipc/uts always unshared. - 4 excluded-command spoofing tests: prefix-only doesn't bypass; pipeline after-excluded DOES bypass (documented as known M5.2-tracked behavior). - 2 sandbox-exec e2e tests on macOS: block /usr/local/bin write; profile parses without syntax error (smoke). - 2 bwrap e2e tests on Linux: block outside-cwd write; DNS unshared when allowedDomains=[]. · packages/core/src/sandbox/profile.ts hardened so e2e tests pass: - Add `(allow file-read* (literal "/"))` and related (literal "/private") entries so shell getcwd / parent stat succeed under deny-default. - Add `(allow file-read* (subpath "/private/var/folders"))` for dyld closure cache (without this, /bin/sh exited with SIGABRT before any command could run). - Add `(allow process-info*)`. · docs/security-model.md (NEW, ~180 lines): threat model, defence layers (trust → modes → permissions → sandbox → plugin subprocess → credentials), hostile-input handling, attack-vector test inventory, explicit list of known gaps (DNS exfil, OS-wrap of plugin process, pipeline analysis, domain whitelist) with milestone tracking. Tests: 308/10 pass/skip in core (was 293), 41 in cli unchanged. Total 349 passing.

If you're reviewing a +PR that touches credentials, sandbox, plugin runtime, or hooks — verify it +against the threat model here. + +## Threat model + +DeepCode is an LLM-driven coding assistant. The threats we care about, in +decreasing order of operator severity: + +| # | Threat | Severity | Where mitigated | +| - | ------------------------------------------------------------------------ | -------- | ----------------------- | +| 1 | Model exfiltrates DeepSeek API key (or other env secrets) via tool call | High | M3.5 sandbox + M5.1 env strip | +| 2 | Model writes arbitrary files outside the project (`/usr/bin`, `/etc`) | High | M3.5 sandbox + permissions | +| 3 | Plugin (third-party code) does either #1 or #2 | High | M5.1 subprocess + (M5.1-ext) OS sandbox | +| 4 | Hook script (third-party shell snippet) does either #1 or #2 | Medium | M3.5 sandbox wraps Bash; hooks bypass when invoked via /bin/sh directly | +| 5 | Hostile `settings.json` field (e.g. allowRead path) injects sandbox rule | Medium | escapeSbpl() | +| 6 | Untrusted project's AGENTS.md drives the agent into harmful action | Low | Trust store (`/trust`) | +| 7 | DNS exfiltration of secrets from sandboxed Bash | Acknowledged limitation | M3.5-ext userspace proxy | + +## Defence layers + +### Layer 0 — Trust store + +First time DeepCode opens a folder, you're asked **"Do you trust this +directory?"**. If you say no, the agent runs in a heavily restricted mode: +no exec, no writes outside the project, no `bypassPermissions` mode allowed. + +Decisions persist in `~/.deepcode/trust.json`. + +### Layer 1 — Mode + Permissions + +Every tool call goes through: + +``` + Mode policy → Permission rules → Sandbox wrap → Exec +``` + +Modes (`default` | `acceptEdits` | `plan` | `auto` | `dontAsk` | `bypassPermissions`): +- `plan` blocks all writes and exec (read/grep/glob only). +- `default` prompts for risky operations. +- `bypassPermissions` is gated behind the trust store. + +Permission rules in `settings.json` are evaluated in order: deny > ask > allow. +4 glob patterns are supported per rule (read/write/edit/exec). See +`packages/core/src/config/permissions.ts`. + +### Layer 2 — Sandbox (M3.5) + +Bash tool invocations are wrapped under platform sandbox when +`settings.sandbox.enabled` is `true`. + +**macOS — `sandbox-exec` + SBPL profile** + +Profile is generated dynamically per invocation (`buildMacOsProfile`) and +written to `$TMPDIR/deepcode-sb-*.sb`. Policy: + +- **Default-deny** on file-read, file-write, and most other operations. +- Allowed reads: `/usr`, `/System`, `/Library`, `/private/etc`, + `/private/var/db`, `/private/var/folders` (dyld closure), `/bin`, `/sbin`, + `/opt`, `/dev`, `~/.config`, `~/.npm`, `~/.cache`. Plus user-provided + `filesystem.allowRead` paths. +- Path traversal: explicit `(literal "/")` and `(literal "/private")` + entries so `getcwd()` and parent stats work. +- Allowed writes: `/private/tmp`, `/private/var/folders`. Plus user-provided + `filesystem.allowWrite` (also implicitly readable). +- `denyRead` / `denyWrite` rules appended LAST so they override allows on + overlap. +- Network: default-allow unless `network.allowedDomains: []` (empty array) + meaning "no network". Domain whitelist needs M3.5-ext (userspace proxy). +- Unix sockets: blocked unless `network.allowUnixSockets: true`. + +**Linux — `bwrap` argv** + +Generated by `buildLinuxBwrapArgs`: + +- System read-only mounts: `/usr`, `/lib`, `/lib64`, `/bin`, `/sbin`, `/etc` + (`--ro-bind-try`). +- `/proc`, `/dev`, `/tmp` (tmpfs). +- cwd is the only bare `--bind` (rw). +- Always `--unshare-pid`, `--unshare-ipc`, `--unshare-uts`. +- `--unshare-net` when `network.allowedDomains: []`. + +**Windows — not supported.** Sandbox is a no-op (see plan §0.2). + +**Excluded commands** — `git` is excluded by default. The match is on the +leading whitespace-bounded token of the user command. Pipelines starting with +an excluded command DO bypass — this is documented behavior pinned by a test, +not an oversight. (M5.2 will add per-clause analysis.) + +### Layer 3 — Plugin subprocess (M5.1) + +Plugins run in their own `node` subprocess with: + +- **No host fs/net access** in plugin code — all capabilities (`fs_read`, + `fs_write`, `bash`, `fetch`) flow via JSON-RPC over stdio back to the host, + which applies its own mode/permission/sandbox stack. +- **Token-protected RPC** — host generates an unguessable token per plugin + spawn; every RPC from the plugin must include it. +- **Env scrub** — `DEEPSEEK_API_KEY` and `DEEPSEEK_AUTH_TOKEN` are stripped + from the child env. Plugins cannot read DeepSeek credentials. +- **Hash pin** — plugin code is SHA-256 hashed at install time; mismatch on + load fails open (drift detection). + +**Acknowledged gaps**: +- The subprocess isn't itself sandbox-wrapped at the OS level yet. A + malicious plugin can still exfil via DNS, can read other files the host + process can read (e.g. `~/.deepcode/credentials.json`). M5.1-ext closes + this by spawning the plugin under `sandbox-exec`/`bwrap` too. +- A plugin can still `process.exit(N)` to crash the host's plugin pool. Host + restarts on next launch. + +### Layer 4 — Credentials + +- API key stored in `~/.deepcode/credentials.json` with `chmod 600`. +- `apiKeyHelper` field can point at an OS keychain wrapper; output is cached + for 5 min (`ApiKeyHelperRefresher`, configurable via + `DEEPCODE_API_KEY_HELPER_TTL_MS`). +- `/doctor` redacts the loaded key in its output (`sk-…` truncated). + +## Hostile-input handling + +The SBPL profile builder treats every user-controlled string (allowRead paths +etc.) as **untrusted**. We: + +1. Escape backslash and double-quote before embedding into a quoted SBPL + subpath literal (`escapeSbpl`). +2.
