Security audit

WhatsApp 排版入门

Security checks for vulnerabilities and agentic risk

Overview

This looks like a WhatsApp formatting guide, but it also contains unrelated claims about file writing, API calls, and command execution that do not fit its stated purpose.

Install only if you want a Chinese WhatsApp formatting reference and are comfortable ignoring the unrelated automation, API, file-writing, and command-execution language. Do not let this skill authorize shell commands, network diagnostics, external API use, or file writes unless you separately asked for those actions and can review them.

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

Findings (7)

Intent-Code Divergence

High
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill explicitly classifies itself as pure Markdown guidance with no execution requirements, yet later instructs the agent to run network diagnostic commands such as ping. This mismatch can mislead reviewers and users about operational behavior, causing an agent to attempt command execution outside the declared scope and tool permissions.

Intent-Code Divergence

High
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill says it does not involve WhatsApp/API calls, but other sections discuss API key handling, external service calls, and communication security as if they are part of normal operation. These contradictory claims can normalize broader data access and network behavior than users expect, increasing the chance of inappropriate secret handling or unreviewed integrations.

Description-Behavior Mismatch

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

A WhatsApp formatting guide should not claim capabilities like file processing, API integration, and system command execution, especially when those capabilities are unrelated to the stated function. This kind of scope inflation is dangerous because it can disguise a broader-behavior skill as harmless documentation, undermining user consent and security review.

Context-Inappropriate Capability

High
Category
Not specified by scanner
Confidence
98% confidence
Finding

Unjustified references to file processing, API integration, and command execution materially expand the apparent privilege and behavior envelope of an otherwise simple text-formatting skill. In agent environments, that can prompt unnecessary access to local files, network resources, or shell features, creating avoidable attack surface.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
92% confidence
Finding

The description says to use the skill for broad activities like '设计创作、UI设计、海报制作、品牌视觉', which are generic design requests rather than narrowly scoped WhatsApp formatting tasks. This makes invocation boundaries unclear and increases the risk that the skill is selected for unrelated work.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The description states '支持中文交互', and the document consistently frames the skill as Chinese-only without offering a language choice. Forcing a specific language or locale without user opt-in can violate organizational language policy requirements.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
89% confidence
Finding

Marketing a simple guide as a high-efficiency automation workflow with batch file handling, API parsing, and multi-interface aggregation creates an inaccurate trust boundary around the skill. Even if no code is present, this misrepresentation can influence agent orchestration and user expectations toward broader, riskier behavior.
