Summary
Bumps Microsoft.RemoteDesktop.Client.MSRDC.SessionHost from 1.2.6676 to 1.2.7214 in packages.config.
This addresses CVE-2026-32157 (a use-after-free RCE in the Remote Desktop client), which was first fixed upstream in MSRDC 1.2.7099. Pinning to 1.2.7214 (latest GA, June 10 2026) also picks up several additional CVE fixes shipped after 7099: CVE-2026-45639, -42908, -42909, -42913, -42992, -44799, -44801, -42985, -47289.
The matching Microsoft.RemoteDesktop.Client.MSRDC.SessionHost 1.2.7214 package has been mirrored to the
WslDependenciesfeed so the build can restore it. Package layout is unchanged (build/native/bin/{x64,x86,arm64}/msrdc.exeplusrdclientax.dll,rdpnanoTransport.dll,RdpWinStlHelper.dlland MUIs), so this is a drop-in version bump.MSRDC_VERSION(used inwsl --version) is derived automatically frompackages.config.Fixes #40868
