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

• Third-party content exposure detected (high risk: 0.75). The required workflow is signature verification and processing of incoming webhook event bodies, which are outsider-authored free text (user-generated messages/events from other parties) that would be parsed/ingested into the agent’s LLM context via request_raw_body_string / events[] if the agent passes those values to the LLM.
