version of 8.0.4xx SDK's were incorrect. MSFT updated the advisory to:
Any installation of .NET 8.0.115 SDK, .NET 8.0.311 or .NET 8.0.312 SDK, .NET 8.0.408 or .NET 8.0.309 SDK or earlier.

but it should read:
Any installation of .NET 8.0.115 SDK, .NET 8.0.311 or .NET 8.0.312 SDK, .NET 8.0.408 or .NET 8.0.409 SDK or earlier.

  • [nitpick] The removal of the CVSS_V3 severity entry suggests a shift to using solely CVSS_V4 for scoring. Please ensure that this change is in line with the intended advisory standard and that affected parties are informed of the update.
