Picks up the September 8, 2026 .NET servicing release (10.0.12). Every
Microsoft.*/System.*package was pinned at 10.0.11, and the twomigration script projects were still on 10.0.8.
Why now
CVE-2026-69304is an ASP.NET Core denial of service via improperlyhandled highly compressed request data. It is unauthenticated and
reachable over the network, so it applies to VIPER directly.
The other CVEs in this release (
CVE-2026-69439,CVE-2026-71328, bothCVSS 8.8 out-of-bounds writes in Portable PDB / MSFZ PDB parsing, plus
CVE-2026-69522,CVE-2026-58649,CVE-2026-69806) sit in PDB-parsingpaths, so they are build and debug tooling rather than the running app.
They are fixed by the same bump.
Changes
17 package references moved to 10.0.12 across
web/Viper.csproj,test/Viper.test.csproj,EffortMigration.csproj, andPhoneListsMigration.csproj. No source changes.Deploy note
The package bump does not close the runtime side on its own. The TEST and
PROD IIS servers need the matching ASP.NET Core 10.0.12 hosting bundle
installed, otherwise
CVE-2026-69304stays open on the deployed app.Verification
