Gumroad Admin

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small Gumroad admin helper that discloses its need for a Gumroad token and its ability to view store data and create discounts.

Install only if you intend to let OpenClaw administer your Gumroad store. Use the least-privileged Gumroad token available, keep the token private, and review any discount creation command before it runs because it can affect live pricing.

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
Content
## Setup

1. Get your Access Token from Gumroad (Settings > Advanced > Applications).
2. Set it: `export GUMROAD_ACCESS_TOKEN="your_token"`

## Commands
Confidence
70% confidence
Finding
Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Missing User Warnings

Medium
Confidence
90% confidence
Finding
The skill exposes a command that can create discounts and directly affect store pricing, but the description and command documentation do not warn users that it performs business-impacting write actions. This increases the chance of accidental misuse, especially in an agent-driven environment where users may assume the skill is read-only administrative reporting.
