From e0419d4183633ba4984081e3b5051d6d229a985e Mon Sep 17 00:00:00 2001 From: cagataycali Date: Wed, 1 Apr 2026 18:45:11 -0400 Subject: [PATCH 01/30] improve: stricter input validation and default loopback in gr00t_inference Improvements to the gr00t_inference tool: 1. Input validation for all user-supplied parameters: - data_config and embodiment_tag validated against strict alphanumeric patterns (they are enumerable values from the docstring). - checkpoint_path and trt_engine_path reject shell metacharacters, null bytes, and '..' traversal components. - container_name validated against Docker naming rules. - dtype values checked against explicit allowlists. - Port range validated (1-65535). 2. Default host changed from 0.0.0.0 to 127.0.0.1 (loopback): - Inference services should default to localhost-only binding. - Users can still explicitly pass host='0.0.0.0' when network access is needed. 3. Process verification for stop action: - Added _is_gr00t_process() to verify a PID belongs to a GR00T inference process before sending signals. - Host-system fallback now uses pgrep -f with the inference_service pattern instead of lsof (which matches any process on the port). --- strands_robots/tools/gr00t_inference.py | 128 ++++++++++++++++++++++-- 1 file changed, 119 insertions(+), 9 deletions(-) diff --git a/strands_robots/tools/gr00t_inference.py b/strands_robots/tools/gr00t_inference.py index 8bfd9c6f..69aaa10f 100644 --- a/strands_robots/tools/gr00t_inference.py +++ b/strands_robots/tools/gr00t_inference.py @@ -12,6 +12,7 @@ """ import os +import re import socket import subprocess import time @@ -40,6 +41,51 @@ def _checkpoints_dir() -> Path: """Default download destination for HuggingFace checkpoints.""" return get_base_dir() / "checkpoints" +# ───────────────────────────────────────────────────────────────────── +# Input validation helpers +# ───────────────────────────────────────────────────────────────────── + +# Characters that must never appear in values interpolated into commands. +_SHELL_META = re.compile(r"[;&|`$(){}\[\]!<>\\'\"\n\r\x00]") + +# Strict patterns for enumerable parameters. +_DATA_CONFIG_RE = re.compile(r"^[a-z][a-z0-9_]{0,63}$") +_EMBODIMENT_TAG_RE = re.compile(r"^[a-z][a-z0-9_]{0,31}$") +_CONTAINER_NAME_RE = re.compile(r"^[a-zA-Z0-9][a-zA-Z0-9._-]{0,127}$") + + +def _validate_path(value: str, label: str) -> None: + """Reject paths containing shell metacharacters, null bytes, or traversal sequences.""" + if "\x00" in value: + raise ValueError(f"{label} must not contain null bytes") + if ".." in value.split("/"): + raise ValueError(f"{label} must not contain '..' path traversal components") + if _SHELL_META.search(value): + raise ValueError(f"{label} contains disallowed characters: {value!r}") + + +def _validate_data_config(value: str) -> None: + if not _DATA_CONFIG_RE.match(value): + raise ValueError( + f"data_config must be lowercase alphanumeric/underscore (got {value!r}).

Fix: add _is_gr00t_host_process() which reads /proc//cmdline directly (same logic as _is_gr00t_process but without Docker) and uses word-boundary regex to prevent partial port matches.

Only reject chars that cause real harm: ; | & ` $ < > \ \n \r \0. 2. Added `from None` to host validation re-raise to suppress chained traceback noise (inner ipaddress.ValueError has no diagnostic value the outer message doesn't already convey). 3. Tightened _is_gr00t_process and _is_gr00t_host_process identification: now requires BOTH `inference_service.py` AND (`python` or `gr00t`) in cmdline. Prevents false-matching unrelated processes like `vim ~/gr00t/notes.md` or conda envs containing 'gr00t'. 4. Test monkeypatch hardened: all TestIsGr00tHostProcess tests now assert the fake Path was actually called (reachability check), preventing silent fallback to real /proc on refactors. 5. Added Linux-only notes on pgrep ERE patterns and _is_gr00t_host_process docstring. ( |$) is ERE syntax that procps-ng defaults to — BSD pgrep may not match correctly. --- strands_robots/tools/gr00t_inference.py | 23 +++++++-- .../groot/test_gr00t_inference_validation.py | 50 ++++++++++++------- 2 files changed, 51 insertions(+), 22 deletions(-) diff --git a/strands_robots/tools/gr00t_inference.py b/strands_robots/tools/gr00t_inference.py index fedc18e9..17bdb817 100644 --- a/strands_robots/tools/gr00t_inference.py +++ b/strands_robots/tools/gr00t_inference.py @@ -47,8 +47,11 @@ def _checkpoints_dir() -> Path: # Input validation helpers # ───────────────────────────────────────────────────────────────────── -# Characters that must never appear in values interpolated into commands. -_SHELL_META = re.compile(r"[;&|`$(){}\[\]!<>\\'\"\n\r\x00]") +# Characters that cause harm in subprocess argv or shell interpolation. +# Narrowed per AGENTS.md review-learnings: quotes/bangs/parens/brackets +# appear in legitimate filesystem paths and all subprocess calls here are +# argv-style (no shell=True), so they pose no injection risk in path values. +_SHELL_META = re.compile(r"[;&|`$<>\\\n\r\x00]") # Strict patterns for enumerable parameters. _DATA_CONFIG_RE = re.compile(r"^[a-z][a-z0-9_]{0,63}$") @@ -127,7 +130,7 @@ def validate_inputs( raise ValueError( f"host must be a valid IPv4 or IPv6 address (got {host!r}).

Host default reverted to 0.0.0.0: Docker's -p port-publish requires the service to bind all interfaces inside the container; 127.0.0.1 inside a container is unreachable from the host. Not a breaking change. 2. Host validation now accepts RFC-952 hostnames (localhost, host.docker.internal) via regex fallback after ipaddress.ip_address() fails. Only truly invalid strings (special chars, empty labels) are rejected. CHANGELOG updated to document hostname acceptance. 3. validate_inputs() now scoped per action: read-only actions (find_containers, list, status, stop) only validate port/host/protocol; mutating actions (start, restart, lifecycle) validate the full surface. Protocol check moved inside validate_inputs() (was hand-rolled outside). 4. pgrep ERE patterns updated to match both '--port N' and '--port=N' forms, preventing silent miss when service uses = syntax. 5. End-to-end regression tests for _stop_service cross-port-kill bug: verifies port=80 does NOT kill a process on port=8000, and port=8000 DOES kill the correct process. Pins the _is_gr00t_process(port=...) guard per AGENTS.md review-learnings. 6.

Updated docstring and inline comments to say 'actions whose only user-controlled surface is port/host/protocol' instead. 2.

Default host changed to 127.0.0.1 (AGENTS.md compliance). Container actions (start/restart/lifecycle) auto-flip to 0.0.0.0 internally since Docker -p port-publish requires bind-all inside the container. Users on non-container paths now default to safe loopback binding. 2. Option-injection guard: repo_url, repo_tag, policy_name starting with '-' are rejected — prevents git option injection (--upload-pack=evil, --config=core.fsmonitor=cmd) via subprocess argv. 3. Host-system fallback (pgrep) now returns a clear error on non-Linux platforms instead of silently reporting 'No service running'. 4. All-numeric hostname guard narrowed to multi-label patterns only — single-label numerics (e.g. '123') are valid per RFC-1123/RFC-952. '127.0.01' (multi-label) is still rejected as an IP typo. 5. Stale comment at validate_inputs() call site removed.

Users on non-container paths now default to + safe loopback binding; pass ``host="0.0.0.0"`` explicitly to expose. +- Option-injection guard: ``repo_url``, ``repo_tag``, ``policy_name`` starting + with ``-`` are rejected (prevents git/docker flag injection via subprocess argv). +- Host-system fallback (pgrep) now returns a clear error on non-Linux platforms + instead of silently reporting success. +- All-numeric hostname guard narrowed to multi-label patterns only — single-label + numerics (e.g. ``123``) are valid per RFC-1123. ### Notes diff --git a/strands_robots/tools/gr00t_inference.py b/strands_robots/tools/gr00t_inference.py index a1bcc267..f04dd47b 100644 --- a/strands_robots/tools/gr00t_inference.py +++ b/strands_robots/tools/gr00t_inference.py @@ -16,6 +16,7 @@ import re import socket import subprocess +import sys import time from pathlib import Path from typing import Any @@ -72,9 +73,10 @@ def _checkpoints_dir() -> Path: r"^[a-zA-Z0-9](?:[a-zA-Z0-9\-]{0,61}[a-zA-Z0-9])?" r"(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9\-]{0,61}[a-zA-Z0-9])?)*$" ) -# Reject all-numeric labels — prevents false-matching typos like "127.0.01" +# Reject multi-label all-numeric strings — prevents typos like "127.0.01" # which pass _HOSTNAME_RE but are clearly malformed IP attempts, not hostnames. -_ALL_NUMERIC_RE = re.compile(r"^[0-9]+(?:\.[0-9]+)*$") +# Single-label numerics (e.g. "123") are valid per RFC-1123. +_ALL_NUMERIC_RE = re.compile(r"^[0-9]+(?:\.[0-9]+)+$") # Factored pgrep pattern — single source of truth for both docker-exec and # host-fallback discovery paths.

Fixed. 2. **Volume path colon injection** — docker -v parses ':' as separator; a volume key like '/legit/dir:rw,nosuid' would be re-interpreted as a mount redirect. Added reject_colon=True to _validate_path for all volume path validations. Also added dash-prefix guard in _validate_path (defense-in-depth for '--privileged=foo' style option injection). 3. **Digest-pinned image references** — _DOCKER_IMAGE_RE now accepts @sha256:<64-hex> as an alternative to :tag (mutually exclusive). Supply-chain recommended practice for image pinning. 4. **Exception chain preserved** — 'from None' changed to 'from exc' in the host validation ipaddress.ip_address try/except. Also expanded the comment to document that _ALL_NUMERIC_RE rejects IPv4 short-forms (not just typos). 5. **TypeError handling** — widened except ValueError to except (ValueError, TypeError) at the validation wrapper boundary. port='5555' (str) no longer propagates as unhandled TypeError. Tests: TestReviewRound8Fixes (8 regression tests) pins all 5 fixes. All 92 validation + 145 gr00t tests pass.
