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.
Dependency Vulnerability Process
The process Particular Software follows for addressing vulnerabilities in dependencies is documented on the Particular docs site.
