Security audit

waitlister

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Waitlister API helper, but it can publish pages and create subscriber records using the user's Waitlister key.

Before installing, understand that actions can create and publish hosted pages, spend AI credits, and add or modify subscriber data in Waitlister. Use a dedicated Waitlister API key and confirm the email address before any verification signup.

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

External Transmission

Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

  1. Check the key first (no side effects, every plan):
bash
curl "https://waitlister.me/api/v1/me" -H "X-Api-Key: $WAITLISTER_API_KEY"
# → plan, waitlists.can_create (a dry run of step 1), ai_credits.remaining
# 401 = key missing, wrong type, or revoked: ask the user, don't probe other endpoints

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
85% confidence
Finding

The skill instructs the agent to submit a real email address to a third-party service and fetch the hosted page as a verification step, but it does not clearly warn that this transmits user data and may create or alter records on an external system. This can cause unintended disclosure of personal data and side effects without explicit user consent, especially because the verification flow goes beyond a harmless read-only check.
