Poyo Flux Kontext

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward PoYo Flux Kontext API helper that discloses its external API use and API key requirement.

Install only if you intend to use PoYo Flux Kontext. Keep POYO_API_KEY in a server-side secret store, and only submit prompts, source image URLs, and callback URLs that you are comfortable sending to 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

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.
