Security checks for vulnerabilities and agentic risk

Overview

This is a coherent English-learning skill that teaches CNN sentence analysis and does not include code, persistence, credential access, or hidden behavior.

Install this if you want Chinese-language help breaking down CNN English sentences. Be aware that when you provide a CNN URL, the agent may try to open that page to retrieve the text; if access fails, the skill instructs it to ask you to paste the passage instead.

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 (1)

Natural-Language Policy Violations

Low

Category: Not specified by scanner
Confidence: 96% confidence
Finding: The instruction says explanations should default to Simplified Chinese, which imposes a language preference on users without explicitly offering a choice. This matches the policy category for language or locale constraints that are not opt-in.
Content: No source excerpt is available for this finding.

Static analysis

No suspicious patterns detected.
