Wishfinity +W
Security checks for vulnerabilities and agentic risk
Overview
The skill appears to provide the advertised wishlist feature, but its setup runs an unpinned third-party MCP package and its activation language is broad enough to need review before installation.
Review the MCP package and publisher before installing, pin a known-good package version where possible, and run the server with minimal local permissions. Users should also configure the agent to invoke Wishfinity only after clear save-to-wishlist intent, not merely when someone says they like a product.
Vulnerability Patterns
- Insecure DependenciesIntroduces malicious components through unsafe dependency sources
- 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

- Finding
The trigger phrases are broad enough to match common conversational language such as 'I want this' or 'Remember this product,' which can cause the agent to promote or initiate a save-flow in situations where the user did not clearly intend to use an external wishlist service. In a shopping-agent context this is more dangerous than in a narrow utility skill because these phrases are likely to appear frequently during ordinary recommendation conversations, increasing the chance of unwanted tool invocation or user redirection to a third-party service.
