### How to know if you are affected

You are affected if you are using previous versions of any of these components, but this doesn't necessarily mean you are vulnerable.

### Symptoms

For NuGet packages your projects have the setting `NuGetAuditMode` set to `all` and see transitive dependency warnings at build time that mention Particular packages.

Other components of the platform will not have any symptoms.

### When to upgrade

You should upgrade immediately if you are affected. Otherwise, you should upgrade during your next maintenance window.
