The cve-2026-114157 tag on WindowsForum.com collects discussion of a Microsoft security advisory for an ASP.NET Core security feature bypass vulnerability affecting ASP.NET Core on Windows. Rated Important, the flaw could allow an attacker with access to a local Windows account to bypass isolation around an affected ASP.NET Core service, potentially reaching data or operations the service exposes. Exploitation depends on winning a race condition, which Microsoft classifies as high complexity. Coverage focuses on the practical response: matching each affected .NET and Visual Studio product branch to its correct fix rather than treating the advisory as one interchangeable update.
