Behavioral Risk Signals
Security Findings2
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | Path Traversal in File Export The `export_to_excel` method directly uses the `output_path` argument without sanitization or validation. An attacker could provide a malicious path (e.g., `../../../etc/passwd` or an absolute path) to write the generated Excel file to an arbitrary location on the filesystem, potentially overwriting critical system files or sensitive user data, leading to data corruption, denial of service, or privilege escalation. Sanitize the `output_path` argument to ensure it is a safe filename and is restricted to a designated, secure output directory. Do not allow absolute paths or path traversal sequences (e.g., `..`, `/`) in user-provided input. A common approach is to only accept a filename and prepend a secure base directory, or use `os.path.basename` and `os.path.join` with a controlled directory. | LLM | SKILL.md:248 | |
| MEDIUM | Missing required field: name The 'name' field is required for claude_code skills but is missing from frontmatter. Add a 'name' field to the SKILL.md frontmatter. | Static | skills/datadrivenconstruction/auto-estimate-generator/SKILL.md:1 |
