Security audit

PKU Info Common

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only PKU authentication helper that discusses sensitive login and session handling, but the behavior is disclosed and fits the stated purpose.

Install this only for work involving PKU IAAA-based CLI tools. Before allowing an agent to log in, reuse sessions, set SMS codes, read keyring entries, or display campus-card/payment QR codes, confirm the task is explicitly PKU-related and that you are comfortable exposing those account materials to the workflow.

Finding
The skill description activates on a very broad set of terms including generic concepts like credential, keyring, session persistence, and QR code display. In an agent system, this can cause the skill to be invoked in unrelated contexts, unnecessarily exposing authentication workflows and credential-handling guidance where it is not needed, which increases the chance of accidental secret access or unsafe action selection.
