expflow-pipeline-hpo

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed ML workflow helper for expflow/PDEBench, with expected cost and credential considerations but no hidden or deceptive behavior found.

Before installing or using it, verify the expflow-pde package/version, keep ClearML and Langfuse credentials in local untracked config, and require an explicit go-ahead before launching HPO, distributed jobs, or pipeline submissions that could spend GPU time or storage.

A.I.G

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

Finding

The trigger phrases are broad enough to match ordinary ML workflow requests such as running HPO, submitting a pipeline, or doing fast iteration. In an agent environment, this can cause unintended activation of a high-impact orchestration skill that submits jobs, consumes GPU resources, or initiates external ClearML workflows without the user explicitly asking for this specific skill.
