Updates the existing record for CVE-2026-102870 after Microsoft's October 25 OOB correction.

  • Correct both Server fixed versions to 10.0.14 and 11.0.0-rc.3.26522.148.
  • Add the standalone DevServer package, which bundles the same affected debugger.
  • Synchronize the description and add the OOB announcement/discussion references.
  • Preserve the existing GHSA/CVE identity, October 13 publication and curated metadata.

Published vendor advisory: GHSA-g27p-qf6j-c96c

OOB announcement: dotnet/announcements#492

Discussion: dotnet/aspnetcore#70039

All four public NuGet packages were downloaded and their fixed debugger contents and producer provenance verified before the vendor advisory was updated.
