Security checks for vulnerabilities and agentic risk

Overview

This skill appears benign: it helps create workplace PPT reports from user-provided materials using a disclosed, confirmation-gated workflow.

Install this only if you are comfortable letting the agent read the specific knowledge base, work records, resume fields, templates, spreadsheets, and images needed for the PPT task. Review generated slides and speaker notes for sensitive personal or company information before sharing, and note that the skill is written for Chinese-language workplace report workflows.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
Findings (6)

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The file presents the skill entirely in Chinese and includes explicit Chinese-only workplace phrasing guidance, but nowhere offers the user a choice of language or states that Chinese is optional. This creates a natural-language locale restriction that could conflict with organizational language policy when users or environments expect another language.

Natural-Language Policy Violations

Medium

Confidence
96% confidence
Finding

The skill metadata and default prompt are written entirely in Chinese and implicitly steer interaction into Chinese without checking the user's language preference. This can reduce user comprehension, weaken informed consent for file access and generation steps, and increase the chance of misunderstandings in a workflow that processes potentially sensitive workplace documents.

Finding

This markdown file presents all instructions, labels, and guidance exclusively in Chinese. Under the stated policy, forcing a specific language without offering the user a language or locale choice is a natural-language policy violation unless clearly justified as region-specific, which is not documented here.
