Mails for Agent

Risk Level: HIGH
Full Analysis
HIGH W007: Insecure credential handling detected in skill instructions.
- Insecure credential handling detected (high risk: 1.00). The prompt explicitly requires making HTTP requests with the header "Authorization: Bearer $MAILS_AUTH_TOKEN" (and using $MAILS_API_URL/$MAILS_MAILBOX), which forces the agent to insert secret token/mailbox values verbatim into requests and outputs, creating an exfiltration risk.
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.85). The skill’s runtime flow can ingest outsider-authored free text from the mailbox via
GET /api/email?id=ID(email body/headers/metadata) and potentially from real-timeGET /api/eventsSSE messages, which are not authored by the operating user.
