WeryAI video tool — anime replace

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrowly scoped WeryAI video-processing helper that discloses its API-key and network use and does not show hidden local file access or persistence.

Install only if you are comfortable sending the provided public video and image URLs to WeryAI and using your WERYAI_API_KEY for potentially paid jobs. Use dry-run first and confirm inputs before submit or wait.

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

Undeclared Tool Scope

Medium

Category: MCP Least Privilege
Confidence: 90% confidence
Finding: The skill invokes a Node.js script that requires both network access and an API key, but the manifest does not declare an explicit tool/permission scope such as allowed-tools or permissions. That omission weakens containment and reviewability: an agent or runtime may grant broader capabilities than reviewers expect, increasing the chance of unintended outbound requests or secret exposure if the packaged script is modified or behaves unexpectedly.
