Summary

  • Fixes [Phase 1.2.1] Replace terminal command blocklist with allowlist #17 -- Replaced terminal blocklist with a strict allowlist approach (CWE-78 mitigation). Only known-safe commands are permitted. Shell escape patterns (subshell expansion, backticks, pipe-to-shell) are blocked regardless of base command. Dangerous subcommands (eval, exec, source) are also blocked. Deployments can extend the allowlist via config.
  • Fixes [Phase 1.2.2] Restrict browser JavaScript execution #18 -- Added pre-execution content checks for browser script action (CWE-94 mitigation). Scripts accessing sensitive browser APIs (document.cookie, localStorage, sessionStorage, indexedDB, XMLHttpRequest, navigator.credentials, crypto.subtle, .getPassword, chrome.identity) are blocked before execution. Wired the guardrails PolicyEngine for risk-level audit logging on all script executions.
  • Security tests for [Phase 1.2.1] Replace terminal command blocklist with allowlist #17 unskipped and implemented (3 tests: shell escape blocking, destructive-command-via-pipe blocking, safe command allowlisting)

Note: This branch is based on richardson/security-hardening and will rebase onto main after #25 merges.

Test plan

  • uv run pytest tests/security/test_terminal_security.py -v -- 3/3 pass
  • uv run pytest tests/ -q --tb=short -- 495 passed, 10 skipped, 0 failures
  • uv run ruff check operator_use/ -- all checks passed
  • Manual verification: confirm destructive commands are blocked (not in allowlist)
  • Manual verification: confirm subshell expansion is blocked (shell escape)
  • Manual verification: confirm browser script with document.cookie is blocked

Action required

1. browser script runs unconfirmed 📎 Requirement gap ⛨ Security
Description
The browser tool executes the script action without any explicit human approval step, allowing
LLM-supplied JavaScript to run immediately. This violates the requirement for human-in-the-loop
confirmation before any browser JavaScript execution.
Code

operator_use/web/tools/browser.py[R292-301]

    case "script":
        if not script:
            return ToolResult.error_result("script is required for script.")
+            _safety_err = _check_script_safety(script or "")
+            if _safety_err:
+                return ToolResult.error_result(_safety_err)
+            risk = _engine.assess("browser", {"action": "script"})
+            logger.warning("Browser script execution -- risk=%s", risk.value)
        result = await page.execute_script(script, truncate=True, repair=True)
        return ToolResult.success_result(f"Script result: {result}")
Evidence
PR Compliance ID 1 requires a human confirmation step before any script action executes. The code
only checks for a few blocked patterns and logs risk, then calls page.execute_script(...) directly
with no approval/confirmation gate.

2. fetch exfiltration not blocked📎 Requirement gap ⛨ Security
Description
The JavaScript restriction blocklist does not include fetch, so executed scripts can still
exfiltrate data via network requests. This fails the requirement to block network primitives (at
minimum fetch/XMLHttpRequest) unless a robust sandbox is enforced.
Code

operator_use/web/tools/browser.py[R19-29]

+_BLOCKED_JS_PATTERNS = [
+    "document.cookie",
+    "localStorage",
+    "sessionStorage",
+    "indexedDB",
+    "XMLHttpRequest",
+    "navigator.credentials",
+    "crypto.subtle",
+    ".getPassword",
+    "chrome.identity",
+]
Evidence
PR Compliance ID 2 requires blocking storage/cookie access and external exfiltration via
fetch/XMLHttpRequest. The implementation blocks XMLHttpRequest but omits fetch, and scripts
still execute in-page via page.execute_script(...) with no sandbox enforcement.

3. Missing malicious JS security tests📎 Requirement gap ≡ Correctness
Description
No automated security tests were added to validate that malicious script payloads (cookie/storage
theft, fetch/XHR exfiltration) are blocked or require confirmation. This makes the new browser
execution controls regression-prone.

+]
+
+
+def _check_script_safety(script_content: str) -> str | None:
+    """Returns an error message if script accesses sensitive APIs, None if safe."""
+    script_lower = script_content.lower()
+    for pattern in _BLOCKED_JS_PATTERNS:

Evidence
PR Compliance ID 3 requires automated tests that attempt malicious script payloads and verify they
are blocked/confirmed/sandboxed. The PR adds script guard logic but introduces no corresponding

4. No ActionValidator for browser.script 📎 Requirement gap ⚙ Maintainability
Description
Browser script execution is not mediated by an ActionValidator guardrail and is instead
implemented ad-hoc inside the browser tool. This prevents centralized, auditable enforcement and

5. Terminal allowlist not config-driven 📎 Requirement gap ⛨ Security
Description
Terminal allowlist customization is documented but not actually wired to config.json, since
terminal() never reads config or passes extra_allowed_commands into _is_command_allowed. This
fails the requirement for deployment-specific configurability.

Evidence
PR Compliance ID 5 requires a configurable allowlist via config.json. Although the code comments

6. Shell-escape checks trivially bypassed 📎 Requirement gap ⛨ Security
Description
Terminal shell-escape blocking relies on simple substring checks and misses common
formatting/evasion patterns (e.g., ; bash, |  bash, |\nsh, or absolute-path shells like `|
/bin/sh`). This violates the requirement to consistently block pipe-to-shell and command-injection
patterns.

Evidence
PR Compliance ID 6 requires blocking pipe-to-shell, command substitution, and dangerous subcommands
consistently and resistant to trivial evasion. The implementation only checks for a few literal
substrings in _SHELL_ESCAPE_PATTERNS against cmd_lower without whitespace normalization/robust
parsing, leaving bypass avenues.

PR Compliance ID 7 requires tests for allowlist behavior and documented evasion techniques
(including spacing tricks and curl-pipe-to-bash). The current tests only cover a small set of cases
and omit the required evasion scenarios.

8. Windows TUI clear crashes 🐞 Bug ≡ Correctness

cli.tui.clear_screen runs subprocess.run(["cls"]) on Windows, which can raise FileNotFoundError
and crash the onboarding TUI when clearing the screen.
Code

The TUI’s clear_screen() uses subprocess.run(["cls"]) under os.name == "nt"; as with restart,
this attempts to execute a non-existent program and can crash the interactive flow.

Evidence
The validator checks a small set of escape substrings and then validates only
_get_base_command(cmd) against _DEFAULT_ALLOWED, while the executor runs the entire string via
cmd /c (Windows) or /bin/bash -c (POSIX). This means separators like ;, newlines, and
arbitrary &&  are not prevented and will be interpreted by the shell.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The new terminal allowlist can be bypassed because it only validates the first command token and still executes through a shell. Shell separators (`;`, newline, `&&`, `||`, pipes/redirections, etc.) allow arbitrary follow-on commands.
## Issue Context
- `_is_command_allowed()` checks only a limited substring list and then allowlists the base command.
- `terminal()` executes via `/bin/bash -c` or `cmd /c`, so separators are honored.
## Fix Focus Areas
- operator_use/agent/tools/builtin/terminal.py[25-78]
- operator_use/agent/tools/builtin/terminal.py[81-103]
## Suggested fix
Choose one:
1) **Best**: Stop using a shell for execution. Parse with `shlex.split()` and run `create_subprocess_exec(base, *args, shell=False)`.
2) If shell execution is required:
- Explicitly reject any metacharacters/separators: `;`, `\n`, `&&`, `||`, `|`, `>`, `<`, `>>`, `2>`, `&`, etc.
- Optionally implement a strict parser that splits on separators and validates *each* command segment’s base command against the allowlist.
3) Add regression tests for examples like `git status; rm -rf /` and `git status && rm -rf /` to ensure they are blocked.

6. Shell-escape checks trivially bypassed 📎 Requirement gap ⛨ Security

Terminal shell-escape blocking relies on simple substring checks and misses common
formatting/evasion patterns (e.g., ; bash, |  bash, |\nsh, or absolute-path shells like `|
/bin/sh`). This violates the requirement to consistently block pipe-to-shell and command-injection
patterns.
Agent Prompt
## Issue description
Shell-escape blocking can be bypassed with spacing/newlines/alternate shell invocation forms because checks are simple substring matches.

## Issue Context
The terminal tool runs `/bin/bash -c` (on non-Windows), so robust blocking is needed to prevent command injection and shell escapes.

Response to Qodo Review — PR #27

✅ Fixed

fetch missing from blocked JS patterns

  • Added "fetch(" and "fetch " to _BLOCKED_JS_PATTERNS — covers fetch('url') and fetch ('url') spacing variant

Missing browser script security tests

  • Added tests/security/test_browser_script.py with 9 tests: cookie access, localStorage, sessionStorage, XHR, fetch exfiltration, credentials API, indexedDB, safe DOM scripts (must pass), and case-insensitive matching
  • All 9 pass

🗣️ Design question for Jeo (not blocking)

Human-in-the-loop confirmation for script execution (Qodo finding #1)
Qodo flags that scripts execute without an explicit user confirmation step. This is correct — the current implementation is a blocklist guard, not a confirmation gate. Full human-in-the-loop (pause execution, send confirmation message to user's channel, wait for approval/denial) is scoped to Phase 2.1 issue #31 in the design doc. Adding a synchronous confirmation gate in Phase 1 would require the channel messaging infrastructure to be wired into the tool execution path, which isn't ready yet. Flagging for Jeo to confirm this phasing is correct before Phase 2 work begins.

Richardson Gunde and others added 13 commits April 5, 2026 20:56
Comprehensive design document covering 5 phases (76 issues):
- Phase 0: CI/CD, test infrastructure, AI principles framework
- Phase 1: Critical security fixes (path traversal, JS injection, terminal, auth)
- Phase 2: AI guardrails & responsible AI (prompt injection, content filtering, ethics)
- Phase 3: Performance benchmarks & optimization
- Phase 4: Comprehensive QA (unit, e2e, adversarial, fuzzing, CI hardening)

Implements GitHub issues CursorTouch#11 and CursorTouch#12:

- AI_PRINCIPLES.md: documents 6 core safety principles (least privilege,
  human oversight, transparency, containment, privacy by default, fail safe)
  with a development checklist for pre-merge security review.

- operator_use/guardrails/: new module providing ActionPolicy, ContentFilter,
  PolicyEngine, and RiskLevel abstractions. Includes DefaultPolicy for
  built-in tool risk classification and CredentialFilter for masking API
  keys in logs and LLM context.

Closes CursorTouch#11, closes CursorTouch#12

  with helpers for traversal/injection payloads (all skipped pending fixes)
- tests/e2e/: message pipeline tests (all skipped pending full stack)

12 tests collected, 0 errors. All skipped with tracking references.

…I cache

- policies.py: Fix browser tool misclassification — tool is 'browser' with
  action arg, not 'browser_script'/'browser_navigate'. script/download => DANGEROUS,
  navigation/interaction => REVIEW (CWE-78 + CWE-22)
- helpers.py + SECURITY_ROADMAP.md: Replace startswith() with is_relative_to()
  for path containment checks — startswith has prefix-collision vulnerability
  where /workspace_evil passes startswith(/workspace)
- ci.yml: Add enable-cache: true to both test and audit setup-uv steps

bandit:
- Remove shell=True from control_center.py and tui.py — pass ["cls"]/["clear"]
  as list args, no shell needed (resolves B602 HIGH)
- Add [tool.bandit] config to pyproject.toml: skip B104 (0.0.0.0 is intentional
  LAN server binding), exclude generated vendored dirs
- Add nosec B324 to restart.py MD5 (filename only, not security)
- Add nosec B310 to fal/openai/together image providers (HTTPS API URLs only)
- Pass -c pyproject.toml in CI so config is loaded

gitleaks:
- Replace gitleaks-action@v2 (requires paid org license for orgs) with free
  gitleaks CLI v8.24.3 downloaded at runtime

pip-audit:
- Upgrade cryptography → 46.0.6, pyasn1 → 0.6.3, requests → 2.33.1,
  tornado → 6.5.5 (all have CVE fixes available)
- Add --ignore-vuln CVE-2026-4539 for pygments (ReDoS, no fix released yet)

The control_center function was hardcoding graceful_fn=None when calling
_do_restart(), ignoring the _graceful_restart_fn kwarg injected by start.py.
This caused test_restart_calls_graceful_fn_not_os_exit to fail and meant
graceful shutdown was never used even when wired.

BrowserPlugin and ComputerPlugin no longer register hooks to the main
agent — subagents manage their own state injection. Test assertions
updated accordingly:
- Remove stale XML-tag assertions from SYSTEM_PROMPT tests
- Fix browser tool name: 'browser' -> 'browser_task'
- Update hook tests: register_hooks() is now a no-op for main agent,
  so assertions verify hooks are NOT wired (not that they are)
