Expanding Sources of Security Advisories and Sightings in Vulnerability-Lookup
#Sightings#CSAF#FKIE#Microsoft#Mastodon#Bluesky
Security Advisories
We’ve recently added new correlating sources for Security Advisories:
- Microsoft CSAF Security Advisories:
https://vulnerability.circl.lu/recent#csaf_microsoft - We’ve also added a new source from Fraunhofer FKIE,
which provides a community reconstruction
of the legacy JSON NVD Data Feeds (at the end it’s more information).
This is accessible at:
https://vulnerability.circl.lu/recent#fkie_nvd
One of the core strengths of Vulnerability-Lookup is its ability to correlate these new sources with existing ones. For example, you can view how vulnerabilities like CVE-2025-21385 appear across multiple sources:
- CVE Project: https://vulnerability.circl.lu/vuln/CVE-2025-21385
- Fraunhofer FKIE: https://vulnerability.circl.lu/vuln/fkie_CVE-2025-21385
- CSAF Microsoft: https://vulnerability.circl.lu/vuln/msrc_cve-2025-21385
Broader Monitoring
We’ve updated some of our monitoring tools (see the Ref. section at the end) to provide a broader view of security advisories discussed across the web and in the news.
Observations:
- Mentions of Red Hat CSAF Security Advisories are notably increasing within the vibrant Infosec.Exchange Mastodon community: https://infosec.exchange
- Security advisories from GitHub (GHSA) and Red Hat CSAF are widely shared on Mastodon but receive minimal attention on Bluesky.
We are also actively monitoring activity related to CERT-FR security advisories on both Mastodon and Bluesky.
As you can see in one of the screenshot, we have as well sightings from bug trackers like Bugzilla. This kind of sighting is made possible thanks to a community of experts willing to share data. So if you think you can contribute, do not hesitate:
