Summary

Improper link resolution before file access in .NET lets an authorized local attacker follow links to escalate privileges (CWE-59). The flaw affects .NET 8.0, 9.0, 10.0 and 11.0 runtimes, Visual Studio 2022 version 17.14 and Visual Studio 2026 version 18.10, and several NuGet runtime packages. The attacker needs local access and low privileges, and no user interaction is required.

Description from the CNA
