Security audit

drillr — Power Terminal for Deep Financial Research

Security checks for vulnerabilities and agentic risk

Overview

The skill has a coherent financial-research purpose, but its documented inline invocation can turn a crafted user question into locally executed Python code.

Review before installing. The safer path is the companion query.py script, invoked with the question as an argument, but the documented inline command should be fixed or avoided. Run only in a sandbox you are comfortable with, and remember that each research question is sent to the drillr.ai public API endpoint.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Undeclared Tool Scope

Finding

The skill executes an inline Python script via a shell and performs outbound network access, but it declares no explicit tool scope or permissions metadata. That mismatch is dangerous because callers and policy systems cannot reliably constrain or review the skill’s actual capabilities, increasing the risk of unintended data egress or policy bypass if the skill is invoked in a broader agent environment.
