Questions

Searching the database

How do I search for a CVE or a package?

Type a CVE id, package name, ecosystem or keyword into the search field. Results include the severity, the affected package, the ecosystem, the disclosure date and the fixed version.

Can I filter by severity or by whether a fix exists?

Yes. The filters on the left narrow the list to critical, high, medium or low vulnerabilities, to a single ecosystem, and to vulnerabilities that have a fix available or none yet.

What does "No fix published" mean?

No patched version has been released for that vulnerability yet. The vulnerability page still shows the affected range and any workaround that can reduce exposure in the meantime.
