OCC Artifact Gallery

Security checks for vulnerabilities and agentic risk

Overview

The skill has a coherent artifact-sharing purpose, but it depends on an unbundled local executable and has broken manifest references that users should review before installing.

Install only in an intended OCC environment where you can verify the referenced artifact_gallery_tool.py, its ownership, permissions, and access controls. Do not use it for sensitive files unless the gallery root allowlist, secret-path rejection, authentication, and link visibility are confirmed.

Vulnerability Patterns
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • 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
