SkillShield's automated analysis identified 5 findings: 1 critical, 3 high, 1 medium, and 0 low severity. Key findings include Arbitrary command execution, Unsafe deserialization / dynamic eval, Dangerous call: subprocess.check_call().
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The Manifest Analysis layer scored lowest at 55/100, indicating areas for improvement.
Last analyzed on February 14, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings5
| 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/wangdinglu/a-share-real-time-data/scripts/setup_and_verify.py:20 | |
| HIGH | Unsafe deserialization / dynamic eval Python builtins/import manipulation Remove obfuscated code execution patterns. Legitimate code does not need base64-encoded payloads executed via eval, encrypted-then-executed blobs, or dynamic attribute resolution to call system functions. | Manifest | skills/wangdinglu/a-share-real-time-data/scripts/setup_and_verify.py:31 | |
| HIGH | Dangerous call: subprocess.check_call() Call to 'subprocess.check_call()' detected in function 'install'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/wangdinglu/a-share-real-time-data/scripts/setup_and_verify.py:20 | |
| HIGH | Dangerous call: __import__() Call to '__import__()' detected in function 'verify'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/wangdinglu/a-share-real-time-data/scripts/setup_and_verify.py:31 | |
| MEDIUM | Unpinned dependency in installation instructions The skill's installation instructions in `SKILL.md` and the `scripts/setup_and_verify.py` script use `pip install mootdx` without specifying a version. This can lead to supply chain vulnerabilities if a future version of `mootdx` or its dependencies (`tdxpy`) introduces malicious code, breaking changes, or security flaws. An attacker could publish a malicious package with the same name, which would then be installed automatically. Pin the `mootdx` dependency to a specific, known-good version (e.g., `pip install mootdx==X.Y.Z`) in both the `SKILL.md` and `scripts/setup_and_verify.py` to ensure deterministic and secure installations. Regularly review and update the pinned version to benefit from security patches and new features. | LLM | SKILL.md:12 |
