Is this an existing test project or a new one using the test templates? Earlier this week a security fix was released for STJ. Additionally, nuget has enabled auditing in .net9 to flag insecure references. Those have combined to lead to this so the app in question needs to be updated (hence me wondering if it's the mstest template or an existing project)?

There was a problem that incorrectly marked STJ 6.x as vulnerable yesterday. Please try again and see if it's fixed. @rbhanda @eiriktsarpalis

The version range was corrected but it took time for nuget/cg to update.

We have double checked and there is no explicit dependency to System.Text.Json from our code (we do use it but not as a package reference so we should pick up the one shipped with the installed runtime).
