Security audit

Abfallkalender RV

Security checks across malware telemetry and agentic risk

Overview

This skill behaves like a disclosed downloader for Ravensburg waste-calendar files, with expected network access and local caching.

Install only if you are comfortable sending the queried address to the Ravensburg Athos portal and storing address-specific calendar files locally. Use --no-cache or clear ~/.cache/abfallkalender-rv if you do not want cache history retained.

MCP Least Privilege
Confidence
87% confidence
Finding
The skill instructs the agent to execute a local Python script that reads and writes files and performs network requests, but the skill declares no permissions. This creates a permission-model mismatch: users or higher-level policy may believe the skill is low-risk while it can access the filesystem, write downloaded content, and contact external services, which weakens transparency and review controls.
