Risk Level: SAFECOMMAND_EXECUTION
Full Analysis
- [COMMAND_EXECUTION]: The skill provides an embedded Python helper script (§10) that executes the system
digcommand viasubprocess.runto perform recursive SPF record lookups.\n- [INDIRECT_PROMPT_INJECTION]: The skill is designed to ingest and process untrusted external data in the form of DNS records, creating a vulnerability surface where malicious records can influence the agent or the diagnostic script.\n - Ingestion points: Raw DNS TXT records (SPF and DMARC) fetched from external domains.\n
- Boundary markers: Not implemented; the skill instructions do not define delimiters to separate untrusted record content from the agent's instructional context.\n
- Capability inventory: The skill enables shell command execution through the provided diagnostic script.\n
- Sanitization: The helper script implements basic string normalization but lacks validation to ensure host strings derived from external records do not contain malicious command arguments (e.g., strings starting with a hyphen).
