Obsidian Sync

Security checks across malware telemetry and agentic risk

Overview

This is a disclosed local sync server that can read and overwrite configured workspace files, so it is appropriate for Obsidian sync but should be configured carefully.

Install only if you want an authenticated sync server that can read and write files in the configured workspace folders. Keep it bound to localhost unless you intentionally expose it, protect the sync token, and narrow SYNC_ALLOWED_PATHS or use backups/versioning if you do not want memory or noncritical files overwritten.

Missing User Warnings

Medium
Confidence
84% confidence
Finding
The skill exposes two-way synchronization and a write endpoint that can modify workspace files, but the documentation does not clearly warn users about overwrite, conflict, or destructive-change risks beyond a brief mention of conflict detection. In a sync tool, unclear safety guidance can lead to accidental data loss or unintended file modification, especially when users expose the service remotely.
