schemathesis

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

• Third-party content exposure detected (high risk: 0.70). The required workflow fetches an OpenAPI schema from a user-supplied URL at runtime (e.g., schemathesis.openapi.from_url("https://your-api/openapi.json") / schemathesis run <schema_url>), and that fetched free-form page/document text is ingested by the tool to generate test cases—an outsider source if the URL/content is not authored by the operating user.

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.80). The skill fetches OpenAPI schemas at runtime (e.g., https://your-api/openapi.json and https://example.schemathesis.io/openapi.json via schemathesis.run and schemathesis.openapi.from_url), and those remote schemas directly drive/alter the tool's test generation and behavior, so they can control agent execution.
