# .NET Aspire: sensitive data leaks into sent messages, enabling local privilege escalation

Link for people: https://infrastack.ai/live/CVE-2026-120006 (this .md is for agents)

.NET Aspire, Microsoft's framework for building distributed .NET apps, inserts sensitive information into data it sends. A local attacker with an existing account can use that exposed information to gain higher privileges.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether your project references Aspire packages, for example `Aspire.Hosting` in your `.csproj` or `Directory.Packages.props`
- Check the installed Aspire version with `dotnet list package`

## Timeline

## From the sources

Insertion of sensitive information into sent data in .NET Aspire allows an authorized attacker to elevate privileges locally.
