CVE-2026-70035
HighCVSS 8.8Summary
A deserialization of untrusted data vulnerability exists in .NET Framework. An unauthorized attacker can exploit this flaw to execute code over a network.
Risk Assessment
An unauthenticated attacker on the network can remotely execute arbitrary code, potentially leading to full compromise of the application and system.
Recommendation
Install the latest security updates for .NET Framework and avoid deserializing data from untrusted sources.
