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

• Third-party content exposure detected (high risk: 0.85). The required workflow converts user-provided .xlsx files (outsider-authored spreadsheet content) into Markdown via scripts/convert_excel_to_md.py using md.convert(...), and then writes/reads that resulting Markdown text into the agent’s LLM context for analysis—so the LLM ingests outsider free text embedded in the workbook.
