Security audit

concur-fpx

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly transparent and read-oriented, but it pairs to a live Concur browser session and includes a generic GraphQL caller that is broader than the stated read-only purpose.

Install only if you are comfortable letting the agent use your signed-in Concur session through fpx. Keep usage to the packaged read queries unless you explicitly intend a Concur change, and review any custom GraphQL file before it is run.

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

This markdown file documents many mutation operations such as deleting expenses, deleting reports, submitting expense reports, and updating report data, but it provides no warning about potential impact to user data or irreversible changes. Under the markdown-specific missing-warning rule, descriptions of behaviors that can affect user data or system integrity should disclose those risks.
