Improper control of generation of code ('code injection') in ASP.NET Core allows an unauthorized attacker to execute code over a network.

PT OCT 2026 - .NET Core, SDK, and ASP.NET Core

The Microsoft Visual Studio Products are missing security updates. It is, therefore, affected by multiple vulnerabilities:

  - Heap-based buffer overflow in Microsoft QUIC allows an unauthorized attacker to execute code over     a network. (CVE-2026-105016)

  - Inconsistent interpretation of http requests ('http request/response smuggling') in ASP.NET Core     allows an unauthorized attacker to perform tampering over a network. (CVE-2026-88092)

  - Inconsistent interpretation of http requests ('http request/response smuggling') in ASP.NET Core     allows an unauthorized attacker to bypass a security feature over a network. (CVE-2026-70188)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Improper control of generation of code ('code injection') in ASP.NET Core allows an unauthorized attacker     to execute code over a network. (CVE-2026-102870)

Note that Nessus relies on the presence of the package as reported by the vendor.
