Trust Assessment
flight-search received a trust score of 10/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 9 findings: 5 critical, 3 high, 1 medium, and 0 low severity. Key findings include Arbitrary command execution, Dangerous call: subprocess.run(), Remote code execution: curl/wget pipe to shell.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The Manifest Analysis layer scored lowest at 0/100, indicating areas for improvement.
Last analyzed on February 13, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings9
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Python shell execution (os.system, subprocess) Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands. | Manifest | skills/awlevin/flight-search/flight_search/cli.py:25 | |
| CRITICAL | Arbitrary command execution Python shell execution (os.system, subprocess) Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands. | Manifest | skills/awlevin/flight-search/flight_search/cli.py:39 | |
| CRITICAL | Arbitrary command execution Python shell execution (os.system, subprocess) Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands. | Manifest | skills/awlevin/flight-search/flight_search/cli.py:70 | |
| CRITICAL | Arbitrary command execution Remote code download piped to interpreter Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands. | Manifest | skills/awlevin/flight-search/install.sh:20 | |
| CRITICAL | Remote code execution: curl/wget pipe to shell Detected a pattern that downloads and immediately executes remote code. This is a primary malware delivery vector. Never pipe curl/wget output directly to a shell interpreter. | Static | skills/awlevin/flight-search/install.sh:20 | |
| HIGH | Dangerous call: subprocess.run() Call to 'subprocess.run()' detected in function 'do_upgrade'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/awlevin/flight-search/flight_search/cli.py:70 | |
| HIGH | Dangerous call: subprocess.run() Call to 'subprocess.run()' detected in function 'detect_installer'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/awlevin/flight-search/flight_search/cli.py:25 | |
| HIGH | Dangerous call: subprocess.run() Call to 'subprocess.run()' detected in function 'detect_installer'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/awlevin/flight-search/flight_search/cli.py:39 | |
| MEDIUM | Unpinned Python dependency version Dependency 'fast-flights>=2.0' is not pinned to an exact version. Pin Python dependencies with exact versions where feasible. | Dependencies | skills/awlevin/flight-search/pyproject.toml |
