Who is impacted?_\nAn Arbitrary File Write vulnerability has been identified in Microsoft's Semantic Kernel .NET SDK, specifically within the `SessionsPythonPlugin`.\nDevelopers who have built applications which include Microsoft's Semantic Kernel .NET SDK and are using the `SessionsPythonPlugin`\n\n### Patches\n_Has the problem been patched? What versions should users upgrade to?_\nThe problem has been fixed in [Microsoft.SemanticKernel.Plugins.Core version 1.71.0](https://www.nuget.org/packages/Microsoft.SemanticKernel.Plugins.Core/1.71.0). Users should upgrade to version 1.71.0 or higher.\n\n### Workarounds\n_Is there a way for users to fix or remediate the vulnerability without upgrading?_\nUsers can create a [Function Invocation Filter](https://learn.microsoft.com/en-us/semantic-kernel/concepts/enterprise-readiness/filters?pivots=programming-language-csharp#function-invocation-filter) which checks the arguments being passed to any calls to `DownloadFileAsync ` or `UploadFileAsync` and ensures the provided `localFilePath` is allow listed.\n\n### References\n_Are there any links users can visit to find out more?_\n-
