PKU CWFW

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed guide for using a PKU financial-portal CLI, but users should treat its saved login sessions as sensitive.

Use this only on a trusted machine/account. The skill is for accessing sensitive payroll and reimbursement data, and its sessions may be saved locally; use the CLI's logout/session controls when finished and avoid shared environments.

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

Missing User Warnings

Medium

Confidence

Finding

The skill explicitly states that authenticated financial-portal session data is persisted under the user's home directory but does not warn about the sensitivity of that data, its lifetime, or the need for filesystem protections. In the context of a payroll/reimbursement portal, locally stored session artifacts could enable unauthorized access to salary, compensation, or reimbursement information if another local user, malware, backup system, or shared environment can read them.

Natural-Language Policy Violations

Confidence

Finding

The note 所有文案中文 instructs that all user-facing text be in Chinese, which imposes a language choice without offering the user a preference or opt-in. This is a natural-language policy concern because it forces a specific locale rather than documenting a justified region-specific exception or providing choice.
