Only that package and its direct TestPlatform dependencies changed:Microsoft.CodeCoverage,Microsoft.TestPlatform.TestHost, andMicrosoft.TestPlatform.ObjectModel, all 18.11.0 → 18.11.1.Why
This is the .NET servicing update of 10 November 2026. SDK 10.0.403 is inside the affected 10.0.4xx range (
>= 10.0.400, <= 10.0.403). The fixed SDK for that band is 10.0.404, which includes runtime 10.0.15.The 10.0.15 release notes list the security fixes in this release, including the DiaSymReader remote code execution fixes and CVE-2026-105544 (VSTest elevation of privilege, GHSA-6856-87hx-p5x7).
Microsoft.NET.Test.Sdk17.14.2 is the patched package on the 17.14 servicing line. This repository is already on 18.11.0. The same advisory fixes that line as 18.11.1 (published 10 November 2026;Microsoft.TestPlatform.CLI18.11.0 → 18.11.1). Moving to 17.14.2 would downgrade the test SDK, so the pin stays on 18.11.CI
rollForwardisdisable.ci.ymlandpublish-nuget.ymlalready install the SDK withactions/setup-dotnetandglobal-json-file: global.json, and CI checksdotnet --versionagainst that pin. No workflow or script hardcodes10.0.403.No target-framework change, no other package updates, and no NuGet publish.
