Life Hack Video

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed WeryAI video-generation helper that uses a local Node script, a WeryAI API key, and fixed WeryAI network endpoints for its stated purpose.

Install this only if you intend to use WeryAI and are comfortable providing WERYAI_API_KEY and sending prompts plus any public image URLs to WeryAI. Before confirming a run, check the model, duration, aspect ratio, and especially generate_audio because one example conflicts with the documented audio-off default.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
95% confidence
Finding

The skill explicitly requires environment secrets and network access, but it does not declare a restrictive tool scope such as permissions or allowed-tools. That increases the chance an agent runtime grants broader capabilities than necessary, making secret exposure or unintended outbound requests harder to constrain or audit.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The invocation description is broad enough to trigger on common creative-video requests, increasing the likelihood this networked, paid, secret-dependent skill is invoked when a narrower or safer path would suffice. Overbroad auto-activation can cause unintended API calls, unnecessary credit consumption, and secret use in contexts the user did not clearly intend.

Content

No source excerpt is available for this finding.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The implicit trigger phrase is broad, natural-language content that can match ordinary user requests about cleaning pet hair or short vertical videos without clearly requiring intentional skill invocation. This can cause the skill to activate unexpectedly, leading to over-triggering, incorrect tool use, or bypass of user intent boundaries in unrelated conversations.

Content

No source excerpt is available for this finding.

Intent-Code Divergence

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill documentation repeatedly states that generate_audio defaults to false, including the confirmation table and parameter configuration. However, the example submission command uses "generate_audio":true, which directly conflicts with the documented intent and could cause the agent to submit parameters inconsistent with what it told the user.
