Security checks for vulnerabilities and agentic risk

Overview

The scanners classify this skill as benign because its reported behavior appears aligned with its media-generation purpose, while noting an unpinned installer command and privacy disclosures to consider; coverage is incomplete because one local reference could not be resolved.

The verdict is benign, not a guarantee of zero risk. Before installing, consider whether you are comfortable with an unpinned installer and with media or text being processed by Varg. The scan inspected two Markdown files but was marked partial because a local reference could not be resolved.

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 (8)

MCP server referenced without pinned version: 'npx skills'.

MCP Rug Pull
Confidence
86% confidence
Finding

The command invokes an unpinned npm CLI and installs skill content from a mutable repository reference. Although this is not an MCP server reference as labeled, compromised or unexpectedly changed upstream content could execute with the installing user's privileges or introduce malicious agent instructions.

Content

No source excerpt is available for this finding.

The media-generation workflow lacks a warning that user-provided content is sent to external services.

Confidence
88% confidence
Finding

The README instructs users to generate a monologue from a local character image and describes a workflow using the varg API and external generation services. Although it names those services, it does not explicitly disclose that supplied images, scripts, and generated media are transmitted for remote processing, which matters when the content is private or sensitive.

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Generation runs on varg: REST `https://api.varg.ai/v2` (the `varg-ai` skill) or the MCP server `https://mcp.varg.ai/mcp`. Price the batch first (`POST /v2/estimate` or `estimate_cost`).

The workflow sends character images and voice audio to an external service without an explicit privacy warning.

Output Handling
Confidence
88% confidence
Finding

The workflow instructs the agent to submit an angle still and an audio segment to Varg for lip-sync generation, potentially using the user's photo and own voice collected in section 1. Although the skill identifies Varg as the generation service, it does not explicitly warn that these potentially identifying materials will be transmitted for remote processing; the voice-consent instruction addresses impersonation rather than this privacy concern.
