Debian Security Advisories
Debian Security Advisories (DSAs) cover the stable Debian distribution, the foundation beneath countless servers, containers and derivative distributions. Because Debian packages are the upstream of so much infrastructure, a DSA is often the clearest signal of which fixed package version actually closes a CVE.
CSIRTS.com ingests Debian Security Advisories every 3 hours, normalizes each advisory into a common schema and cross-references every CVE against the CISA KEV catalog and public exploit datasets. Publishes DSA advisories for Debian stable packages. Also available via RSS, JSON API and the MCP server.
