Inspect sensitive data retrieved through connectors mid-workflow

.md .json

Acceptance criteria

Detect when an agent picks up sensitive content from one connnected tool and attemps to share it with a separate tool, even if the user prompt was benign.

Why it matters

Connectors pull sensitive data into a conversation even when the user's question is harmless.

How to verify

When an agent picks up sensitive information from one tool or dataset and attempts to share it with a different tool, the even is blocked if it violates policy.

OWASP adoption context

Embedded assistants, integrated platforms, citizen workflows and MCP extensions can retrieve sensitive data after a benign prompt; inspect the returned payload.

Framework mappings

  • Inspecting connector payloads reveals sensitive information entering a workflow even when the prompt is benign, supplying runtime evidence for transfer, confidentiality and leakage controls. Detection alone does not restrict later disclosure; finding sensitive content also does not establish poisoned context. SOC 2: C1.1: The Confidentiality category and relevant information must be in scope. ISO/IEC 27001: A.8.12: Operate inspection within a leakage-protection workflow with defined alert triage, warnings, blocking or another protective response.

  • Where retrieved content includes personal data, the findings inform examination of privacy risk within the AI workflow. Recognizing sensitive content is one input to that examination, not a complete privacy-risk assessment.
