Today we’re releasing Vulnerability-Lookup 4.0.0, and this is a big one.

🔄 Remote Instance Synchronization

This version is paving the way for federated deployments of Vulnerability-Lookup instances.
You can now synchronize multiple Vulnerability-Lookup instances and share:

• 💬 Comments
• 📦 Bundles
• 👁️ Sightings
• 🚨 KEV entries (GCVE BCP-07)

This introduces a true federated model for vulnerability intelligence sharing.

Let’s take a look at all the notable changes.

🔁 Remote Instance Synchronization – What’s Inside

This release introduces a complete sync engine designed for reliability, transparency, and operational control.

A local instance can now pull objects — including bundles, comments, sightings, and KEV entries — from configured remote Vulnerability-Lookup instances via their public APIs.

The synchronization engine includes:

• Remote instance management with per-object-type synchronization controls
• Timestamp-based update detection to keep data consistent
• Asynchronous scheduler with graceful shutdown support
• CLI command and systemd service template for automation
• Administrative controls to trigger synchronization manually
• Visual indicators in the interface to clearly identify synchronized objects

🔌 Feeder Improvements

Expanded data ingestion:

• New RustSec OSV feeder
• New OSS-Fuzz feeder (with YAML support in OSV)
• More generic CSAF and OSV templates

This strengthens Vulnerability-Lookup’s position as a correlation hub across heterogeneous vulnerability sources.

🎨 UI Improvements

• Redesigned global dashboard layout for better visibility and structure.
