WeryAI video tool — extend

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrowly scoped WeryAI video-extension helper that discloses its paid network API use and API-key requirement.

Install only if you are comfortable sending the provided public video URL, prompt, and your WERYAI_API_KEY to WeryAI for a paid generation request. Use dry-run first and confirm the URL, prompt, duration, style, and resolution 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
Vulnerability Patterns
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • 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

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
94% confidence
Finding

The skill requires access to both environment secrets and the network, but it does not declare an explicit tool scope such as allowed-tools or permissions. That creates ambiguity about what the executing agent may invoke and increases the risk of unintended tool use, broader capability exposure, or accidental secret handling beyond the narrow documented workflow.
