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

• Third-party content exposure detected (high risk: 0.80). The skill demonstrates reading and scanning data directly from public cloud storage URIs (e.g., s3://bucket/..., gs://bucket/..., via Polars, fsspec, and PyArrow dataset calls shown in the examples), so it ingests arbitrary third-party files that may be untrusted or user-provided and could carry indirect prompt injections.
