Layer Breakdown
Behavioral Risk Signals
Security Findings2
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| HIGH | Arbitrary File Write via Unsanitized Path The `export_to_excel` function directly uses the `output_path` parameter to write an Excel file without any validation or sanitization. An attacker controlling this parameter could specify an arbitrary file path, potentially overwriting sensitive system files, writing to unauthorized locations, or causing a denial of service if the skill's execution environment allows such file system operations. This constitutes an arbitrary file write vulnerability. Implement strict input validation for `output_path` to ensure it points to an allowed, sandboxed directory. Alternatively, restrict the skill's file system permissions to only specific, safe directories, or return the file content directly instead of writing to a path. | LLM | SKILL.md:281 | |
| 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/cwicr-material-procurement/SKILL.md:1 |
