Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only CloudBase WeChat payment integration skill that keeps credentials out of chat/source and scopes payment work to user-directed setup, code changes, and troubleshooting.

Install only if you want an agent to help with CloudBase WeChat payment/OAuth work. Review generated payment and callback code carefully, keep merchant/AppSecret/AppKey material in CloudBase or WeChat console configuration, and require real-payment or deployment steps to be explicitly user-approved.

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
Vulnerability Patterns
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Autonomous Decision Making

Excessive Agency
Confidence
80% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

1. Treat Integration Center creation as a console-first workflow unless a public Manager SDK or Cloud API contract is confirmed in official docs.
2. Use official `index.md` docs for console UI steps and credential fields; do not copy stale console screenshots or invent field names.
3. Never ask the user to paste secrets into chat. Tell them to configure merchant and official-account credentials in the CloudBase console Integration Center form.
4. Do not assume generated function names are fixed. `pay-common` and `offiaccount-common` are examples; ask for or inspect the actual function name before writing calls.
5. Treat frontend payment success as UI feedback only. The authoritative payment state must come from server-side query results or payment callbacks.
6. When extending generated functions, preserve credential environment variables and generated callback verification/decryption logic. Add business logic around order checks, persistence, idempotency, and fulfillment.
