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 instructs the client to fetch an Agent Card from third-party URLs (ClientFactory.createFromUrl fetches baseUrl/.well-known/agent-card.json in SKILL.md and references/sdk-api.md) and accepts remote file URLs in Message Part.file.url (references/protocol-spec.md), which are untrusted external content that the agent is expected to read and that can change transport selection and task-handling behavior.
