Security audit

caldav-sync

Security checks across malware telemetry and agentic risk

Overview

This is a coherent CalDAV calendar and task tool, with real write/delete power and locally stored credentials that users should handle carefully.

Install only if you are comfortable giving the skill access to read, create, update, and delete events and todos in the configured CalDAV accounts. Prefer app-specific passwords or authorization codes, use HTTPS-only CalDAV URLs, double-check account/calendar targets before delete commands, and protect or remove the local .env and cache files when no longer needed.

Missing User Warnings

Medium
Confidence
82% confidence
Finding
The skill exposes delete-event and delete-todo operations but does not prominently warn that these actions may permanently remove calendar data or require confirmation before execution. In a tool that manages real user calendars across multiple accounts, this increases the risk of accidental destructive actions and cross-account mistakes.
