Microsoft Security Advisory CVE-2026-102870 - ASP.NET Core Remote Code Execution Vulnerability
Executive summary
Microsoft is releasing this security advisory to provide information about a vulnerability in the Blazor WebAssembly debugger included in Microsoft.AspNetCore.Components.WebAssembly.Server. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.
The Blazor WebAssembly debug proxy evaluates debugger expressions by generating and compiling C# source. Certain values originating in the application being debugged, including ToString() results, descriptions, and class names, are embedded in that generated source without consistent escaping. An attacker-controlled value can escape the generated string literal and execute code on a developer's machine when the developer evaluates an expression during debugging.

Critical: .NET 10.0 security, bug fix, and enhancement update
.NET is a fast, lightweight and modular platform for creating cross platform applications that work on Linux, macOS and Windows. It particularly focuses on creating console applications, web applications and micro-services. .NET contains a runtime conforming to .NET Standards a set of framework libraries, an SDK containing compilers and a 'dotnet' application to drive everything.

dotnet8, dotnet10, dotnet11 vulnerabilities
It was discovered that the .NET Blazor WebAssembly debug proxy did not properly escape certain values. An attacker could possibly use this issue to execute arbitrary code. The fix for this CVE was originally released via USN-8942-1, but it was found to be incomplete. This issue only affected dotnet10 and dotnet11. (CVE-2026-102870)
It was discovered that the Brotli decompression library used by .NET incorrectly handled certain compressed streams. A remote attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2026-111497)
Alen Cheung discovered that .NET did not properly handle file ownership in certain circumstances. An attacker could possibly use this issue to elevate local privileges. (CVE-2026-114148)
