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

Third-party content exposure detected (high risk: 0.75). Outsider-authored free text can enter the LLM context via the runtime path where the user-provided .xlsx file is parsed and its cell text (from xl/sharedStrings.xml and xl/worksheets/sheetN.xml) is rendered into Markdown/text/JSON and then returned to the agent for inclusion in the conversation.
