Meme Master

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent meme-chat behavior guide with no executable code or network behavior, though users should opt in before allowing saved or passively collected meme libraries.

Install only if you want the agent to handle memes conversationally. Before enabling library features, decide whether meme saving is allowed, turn off passive collection unless you explicitly want it, and periodically review or delete <workspace>/memes/ and meme-index.md.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
86% confidence
Finding

The explicit activation examples for image-analysis mode are all in Chinese, and the response-style examples are also exclusively Chinese. This creates a natural-language policy concern because the skill appears to privilege a specific language without opt-in or stating that it is intended only for a Chinese-language environment.

Missing User Warnings

Medium
Category

Confidence
95% confidence
Finding

The skill explicitly permits saving user-provided memes and passively encountered images, plus maintaining usage metadata such as last-used timestamps and counts, without requiring notice, consent, or retention limits. Even though it advises avoiding private or sensitive content, this still creates a privacy risk because images and interaction metadata can reveal personal preferences, relationships, and potentially identifying context if stored by default.
