Vrbo Vacation Rentals

Security checks across malware telemetry and agentic risk

Overview

This skill is a straightforward Vrbo rental search integration, with the main caveat that it asks users to persist an API key without much secret-handling guidance.

Install only if you are comfortable giving the skill access to a StayingAPI key for rental-search requests. Prefer a stay_test_ sandbox key for evaluation, store live keys in a secure secret manager or protected environment file when possible, and avoid committing the key to repositories or synced dotfiles.

Missing User Warnings

Medium
Confidence
93% confidence
Finding
The document tells users to persist `STAYINGAPI_KEY` across sessions in shell profiles or agent-managed env files, but it does not warn that API keys are sensitive secrets that may be exposed through dotfile syncing, shared machines, process inspection, logs, backups, or repository commits. In an agent/tooling context, encouraging long-lived plaintext credential storage without guidance on least privilege or secure secret storage increases the chance of credential leakage and downstream unauthorized API use.
