Risk Level: MEDIUM
Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.90). The skill explicitly fetches and ingests arbitrary public web content (e.g., SKILL.md commands like
firecrawl scrape "<url>",firecrawl crawl "<url>",firecrawl search "...",firecrawl browser "open <url>") and itsfirecrawl agentLLM extraction processes that untrusted third‑party content (see SKILL.md and rules/security.md), so webpage content could contain instructions that materially influence agent actions.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). The skill explicitly fetches arbitrary user-specified URLs at runtime (e.g., the argument passed to "firecrawl scrape" and "firecrawl agent --urls"), and those fetched pages are ingested by the agent workflow so remote content can directly influence prompts/instructions, meeting the criteria for a runtime external dependency that can control agent behavior.
