Garden Grow Video

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed WeryAI video-generation helper that uses a local Node script, an API key, and network calls in ways that match its purpose.

Install only if you are comfortable using a paid WeryAI API key. Review any WERYAI_BASE_URL or WERYAI_MODELS_BASE_URL environment overrides before use, and confirm generation parameters before spending credits.

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
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
95% confidence
Finding

The skill requires environment access and outbound network use to submit prompts and a bearer token to external WeryAI endpoints, but it does not declare an explicit tool scope such as permissions or allowed-tools. That omission weakens sandboxing and reviewability because a host may permit broader execution/network behavior than users expect, especially given the documented support for URL overrides that could redirect sensitive data to untrusted hosts.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The implicit trigger example is broad and maps a generic gardening-video request directly to this skill without strong disambiguation criteria. This can cause the skill to activate on loosely related prompts, leading to unintended tool use, reduced routing precision, or execution in contexts where another skill or a plain response would be more appropriate.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

This JavaScript file contains natural-language documentation entirely in Chinese, including command descriptions and environment variable guidance, which effectively imposes a specific language on users. Under the policy, locale or language constraints should either be optional for the user or clearly justified as region-specific; neither is present here.
