MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.90). The SKILL.md explicitly sends HTTP requests to user-supplied webhookUrl and polls external APIs (see "Webhook Testing" fetch(webhookUrl) examples and the polling scenarios / context "monitor_external_api"), and it reads and interprets response bodies to decide test outcomes—so it clearly ingests untrusted third‑party content that can influence agent behavior.
