CPA — Client Document Chase

Security checks for vulnerabilities and agentic risk

Overview

This document-chasing guide needs review because it encourages contacting third parties about sensitive client records without checking client permission.

Confirm client permission, recipient identity, and allowed disclosures before contacting a spouse, bookkeeper, or other document holder. Use approved secure channels, and keep extension, incomplete-delivery, and disengagement decisions under practitioner control.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding

The workflow directs the agent to contact the actual document holder, explicitly including a spouse or bookkeeper, without first verifying that the client has authorized that contact and the associated disclosures. A document request can reveal the engagement, financial holdings, or missing tax information to an unauthorized third party; the sensitive CPA context makes this omission consequential, although no malicious destination or deliberate exfiltration is specified.
