Obsidian Sync

Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed Obsidian sync server that can read and write configured workspace files, so it appears safe when installed intentionally and configured carefully.

Install this only if you want a local service that can read and overwrite files in the configured workspace folders. Keep it bound to localhost unless you deliberately expose it through a protected channel, use a strong unique token, narrow SYNC_ALLOWED_PATHS where possible, and keep backups or versioning for notes you care about.

Missing User Warnings

Medium
Confidence
88% confidence
Finding
The skill exposes explicit remote read/write file-sync endpoints, including a write API, but the documentation does not clearly warn users that misconfiguration, token compromise, or unsafe exposure can modify or overwrite local notes and workspace data. Because this is a sync server intended to bridge an agent workspace with an Obsidian vault, the context increases risk: users may treat it as routine tooling while granting it access to sensitive notes.
