Security audit

Vadivelu Memes

Security checks for vulnerabilities and agentic risk

Overview

This is a simple meme-generation skill with minor scope and third-party image-source caveats, not evidence of malicious behavior.

Install only if you are comfortable with a light meme skill that may show third-party hosted images and may activate for somewhat broad Tamil comedy or Indian celebrity meme requests. It does not appear to access private data, install dependencies, persist changes, or run unsafe commands.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Confidence

Finding

The manifest says to use the skill for "random meme generation" and "Indian celebrity memes," which are broad categories that overlap with many unrelated meme requests beyond Vadivelu/Kaipulla content. This ambiguity could cause unintended invocation because the trigger scope is not tightly limited to the specific character/style the skill is meant to handle.

Vague Triggers

Confidence
90% confidence
Finding

The instruction to invoke the skill for "Tamil comedy" or "kaipulla" content is not specific enough to distinguish this skill from other Tamil comedy or meme-related skills. Because no negative examples or exclusion conditions are provided, the activation boundary is unclear and may lead to accidental use for general Tamil comedy requests.

Missing User Warnings

Confidence

Finding

The workflow allows fetching content from external public meme APIs without warning the user or documenting trust boundaries, which can expose users to third-party content, tracking, or unexpected/off-brand material. While not highly dangerous in a meme skill, external fetch behavior still introduces supply-chain and privacy risk because remote content is outside the skill author’s control.
