SCVD Personal Shopper

Security checks for vulnerabilities and agentic risk

Overview

This skill gives careful, user-controlled instructions for making an SCVD x402 purchase, with payment risks disclosed and bounded by approval steps.

Install only from a source and version you trust, and inspect the referenced wallet skill before connecting funds. Use this skill only for a specific purchase you requested, verify the quote and network, keep the spend ceiling at the approved amount, and never paste seed phrases, private keys, recovery tokens, or API credentials into chat.

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

Finding

The skill instructs the host to install and execute a remote package via npx skills add coinbase/agentic-wallet-skills without pinning a specific version or immutable reference. Because this skill handles wallet setup and payment-related flows, a compromised or changed upstream package could alter behavior, exfiltrate sensitive wallet context, or introduce unsafe payment actions at install/use time.
