16,379 advisories

Each date says whether the vendor published or updated the bulletin. A vendor bulletin describes products that may be affected. It does not prove that the vulnerable product or version is installed in your environment.

Before you act

Start with the vendor's bulletin.

We normalize the fields that vendors publish so you can search and compare advisories in one place. We do not replace the original bulletin or turn a product-name match into proof that a system is vulnerable.

Confirm the installed product and version, read the linked vendor guidance, and test the recommended update or mitigation through your normal change process.
