sn-report-format-discovery

Security checks for vulnerabilities and agentic risk

Overview

This skill only chooses a short output-format label for a research request and does not run code, access files, use credentials, or persist data.

This appears safe to install for lightweight report-format discovery. Users should know the instructions are written in Chinese, but the behavior is narrow and does not grant access to local data, network resources, credentials, or persistent storage.

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

Medium

Category: Not specified by scanner
Confidence: 88% confidence
Finding: The skill file is written entirely in Chinese and gives no indication that users may choose another language or that the skill is intended only for a Chinese-language context. This creates a natural-language locale policy concern because it implicitly constrains interaction language without explicit opt-in or justification.
Content: No source excerpt is available for this finding.
