Security audit

PVPC España

Security checks across malware telemetry and agentic risk

Overview

This skill is a bounded Spain electricity-price helper that runs local scripts and queries a disclosed public ESIOS API without credentials, persistence, or private data access.

Reasonable to install if you want PVPC electricity-price guidance for Spain. It will make online requests to the public ESIOS/REE API when used, and users should be aware that holiday tariff-period recommendations may be inaccurate unless they account for holidays themselves.

Finding
El skill declara ejecución de scripts que consultan una API pública de ESIOS, lo que implica capacidad de red sin permisos declarados. Esto es riesgoso porque el agente podría realizar llamadas externas no transparentes para el usuario o para la plataforma, ampliando la superficie de exfiltración, seguimiento o dependencia de servicios remotos, aunque en este caso el contexto apunta a una API legítima y de bajo riesgo.
