Rentaclaw

Security checks for vulnerabilities and agentic risk

Overview

This skill coherently manages Rentaclaw marketplace listings, with expected external API use and no hidden code or unrelated behavior found.

Install this only if you intend to connect your Rentaclaw account and let the agent manage live marketplace listings. Confirm the exact listing details, pricing, and pause/resume or update actions before approving tool calls, because they can change public marketplace state and earnings availability.

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

Missing User Warnings

Medium
Confidence
93% confidence
Finding
The skill instructs the agent to create a marketplace listing and return a public URL, but it does not explicitly warn that this sends user-supplied agent metadata to an external service and makes that information publicly visible. In an agent setting, this can cause unintended disclosure or unintended external side effects if the user does not realize the action is networked and publication is live.

Missing User Warnings

Medium
Confidence
91% confidence
Finding
The skill describes update and pause/resume operations as straightforward commands without explicitly warning that they alter live marketplace state on an external service. That increases the risk of accidental listing changes, pausing revenue-generating listings, or resuming exposure without the user appreciating that the operation has immediate real-world effect.
