v18.12.0
Security fix
This release includes the fix for CVE-2026-105544, an elevation of privilege vulnerability in the VSTest artifact post-processor. The post-processor could consume a forged executionComplete.json written by another local user, and then run attacker-controlled output handling.
Affected: Microsoft.TestPlatform.CLI 18.11.0 and earlier. Every version from 18.11.1 on is fixed, including 18.12.0.
Microsoft.TestPlatform.CLI is the VSTest build that we ship into the .NET SDK. The recommended way to get this fix is to update your .NET SDK to the latest patched version, see the advisory for the SDK versions.
The fix is also released in the Microsoft.TestPlatform.CLI package, for completeness. That package is rarely used directly. It is not a dependency of Microsoft.NET.Test.Sdk or Microsoft.TestPlatform, so those packages do not bring it in.
