Vulnerability-Lookup facilitates quick correlation of vulnerabilities from various sources, independent of vulnerability IDs, and streamlines the management of Coordinated Vulnerability Disclosure (CVD). Vulnerability-Lookup is also a collaborative platform where users can comment on security advisories and create bundles.
A Vulnerability-Lookup instance operated by CIRCL is available at https://vulnerability.circl.lu.
- API: A comprehensive and fast lookup API for searching vulnerabilities and identifying correlations by vulnerability identifier.
- Feeders: Modular system to import vulnerabilities from different sources.
- CVD process: Management of Security Advisories and Vulnerability Disclosures.
- Support of local vulnerability source per Vulnerability-Lookup instance.
- Global CVE Allocation System: Support of the Global CVE Allocation System (GCVE).
- Sightings: Users have the possibility to add observations to vulnerabilities with different types of sightings, such as: seen, exploited, not exploited, confirmed, not confirmed, patched, and not patched.
- Comments: Ability to add, review and share comments on vulnerability advisories.
- Bundles: Possibility to create bundles of vulnerability advisories with a description.
- RSS/Atom: An extensive RSS and Atom support for vulnerabilities and comments.
- EPSS: Integration of the Exploit Prediction Scoring System.
- Track vulnerabilities with your custom product watch lists and receive email notifications.

Vulnerability-Lookup facilitates the recording of vulnerability sightings, regardless of whether they have been published by a source. A suite of sighting clients is already available to support this functionality:
Our tools on the Python Package Index (PyPI):
| Tool | Description |
|---|---|
| ShadowSight | A client that retrieves vulnerability observations from the The Shadowserver Foundation and pushes them to a Vulnerability-Lookup instance. |
| FediVuln | A client to gather vulnerability-related information from the Fediverse. |
| BlueSkySight | A client to gather vulnerability-related information from Bluesky. |
| MISPSight | A client that retrieves vulnerability observations from a MISP server and pushes them to a Vulnerability-Lookup instance. |
| NucleiVuln | A client designed to retrieve vulnerability-related observations from the Nuclei Git repository of templates and pushes them to a Vulnerability-Lookup instance. |
| ExploitDBSighting | A client that retrieves vulnerability observations from Exploit-DB and pushes them to a Vulnerability-Lookup instance. |
| KEVSight | A client to generate sightings for Vulnerability-Lookup from the Known Exploited Vulnerabilities (KEV) catalog. |
| GistSight | A client for gathering vulnerability-related information from GitHub Gists. |
If you want to create your own sigthing tool, it's recommended to use PyVulnerabilityLookup, a Python library to access Vulnerability-Lookup via its REST API.
Generally speaking, requirements are the following:
- Recent version of Python 3.10
- Recent version of Poetry
- Kvrocks database
Installation instructions are available in the documentation.
