Security audit

ALab Experiment Worker

Security checks for vulnerabilities and agentic risk

Overview

This skill is a scoped ALab experiment-worktree helper that discloses its ability to read visible experiment evidence, edit task files, run evaluations, and submit results while explicitly avoiding admin/root authority and raw secrets.

Install this only for agents that are meant to work inside ALab experiment worktrees. Before submission-capable tasks, make sure the agent is operating on the intended worktree and token context, and review final edits/runs if you do not want autonomous experiment submission.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Finding

The skill enables allow_implicit_invocation without defining trigger constraints or exclusions, which can cause the agent to invoke this skill automatically in contexts the user did not explicitly intend. Because this skill can inspect, modify, evaluate, and submit ALab experiment worktrees, unintended invocation could lead to unauthorized changes, accidental submissions, or leakage of visible experiment evidence within the current token context.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
84% confidence
Finding

The file is a Chinese-language command/reference guide and the required final reply format at the end is written as a directive for the worker's response content, with no indication that the user may choose another language. This can create a locale-policy issue because it effectively forces a specific language without documenting opt-in or offering a language choice.
