WeChat Publisher

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed WeChat publishing CLI that uses official WeChat APIs and requires explicit commands for account changes.

Install only for a WeChat public account you are authorized to manage. Treat the AppID/AppSecret, article drafts, uploaded media, analytics, and comments as sensitive, and review commands carefully before using --confirm for publishing or deletion.

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

Confidence
100% confidence
Finding
Referenced artifact was not completely inspected

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
User-facing docstrings, errors, help text, and prompts are all written in Chinese, and the tool does not provide any language or locale selection. This effectively forces a specific language experience without user opt-in, which matches the stated natural-language policy violation criteria.

External Transmission

# ── Constants ─────────────────────────────────────────────
WECHAT_API_BASE = "https://api.weixin.qq.com/cgi-bin"

Confidence

Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Confidence
70% confidence
Finding
Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.

Missing User Warnings

Low
Confidence
83% confidence
Finding
This code retrieves WeChat article statistics and comment data from remote APIs and immediately prints the full JSON responses to stdout. While the network activity is inherent to the tool's purpose, there is no user-facing disclosure that these commands may surface potentially sensitive engagement or comment data in terminals, logs, or pipelines.
