I found a bunch of potential vulnerabilities in the example Skills .py files provided by Anthropic. I don't believe the CVSS/Severity scores though:

| Skill | Title | CVSS | Severity |

| webapp-testing | Command Injection via `shell=True` | 9.8 | *Critical* |

| mcp-builder | Command Injection in Stdio Transport | 8.8 | *High* |

| slack-gif-creator | Path Traversal in Font Loading | 7.5 | *High* |

| xlsx | Excel Formula Injection | 6.1 | Medium |

| docx/pptx | ZIP Path Traversal | 5.3 | Medium |

| pdf | Lack of Input Validation | 3.7 | Low |
