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.md explicitly instructs the agent to call GMAIL_FETCH_EMAILS and GMAIL_FETCH_MESSAGE_BY_MESSAGE_ID (see "Search and Filter Emails" and "Reply to a Thread") to retrieve full message payloads and attachments from users' mailboxes, clearly ingesting arbitrary user-generated/untrusted email content that can influence subsequent tool use and decisions.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). The skill explicitly requires connecting to the Rube MCP server at https://rube.app/mcp and calling RUBE_SEARCH_TOOLS at runtime to fetch tool schemas that directly determine available agent tools/instructions, so this external endpoint can control agent behavior.
