Airbnb prices & cross-OTA comparison
Security checks for vulnerabilities and agentic risk
Overview
This skill is a disclosed StayingAPI integration for Airbnb price checks, with normal API-key and network requirements but no hidden code or unrelated behavior found.
Install only if you intend to use StayingAPI for Airbnb price checks. Prefer a sandbox key for testing, store any live key in your agent or OS secret store when available, avoid pasting keys into chats or logs, and revoke or rotate the key if you think it was exposed.
Vulnerability Patterns
- Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
- 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
