CVE-2026-102869

Summary

A type confusion vulnerability in .NET and Visual Studio allows attackers to exploit resource access patterns that don't match their expected types, enabling unauthorized privilege elevation over a network. This occurs when the system incorrectly handles objects with incompatible types, potentially leading to arbitrary code execution or complete system compromise.

Exploitability

Exploitation requires a network-based attack with minimal preconditions, as the vulnerability affects unauthenticated remote access to .NET and Visual Studio components, making it relatively straightforward to exploit with basic network connectivity.

Blast radius

If exploited, this vulnerability could allow attackers to gain full administrative privileges on affected systems, potentially leading to complete system compromise, data exfiltration, or lateral movement within the network.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

No fixed version is published. Disable the affected feature or restrict access to the named endpoint until a patch is available.
