Poyo Omni Flash

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed PoYo Omni Flash API helper that only sends user-prepared video generation payloads when explicitly requested.

Install only if you intend to use PoYo Omni Flash. Treat POYO_API_KEY as a secret, review payload JSON before submitting, and avoid sending private prompts, media URLs, or callback URLs unless you are comfortable sharing them with PoYo.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
Findings (12)

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
88% confidence
Finding

The skill declares shell-capable execution via required curl usage and explicitly references a submission script, but it does not define any tool scope restrictions such as permissions or allowed-tools. In an agent setting, this weakens least-privilege controls and can enable unintended command execution or broader shell access than the skill actually needs.
