CVE-2026-102869: .NET and Visual Studio Elevation of Privilege Vulnerability

HighCVSS 8.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 35/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.83% (FIRST EPSS); higher than 58.1% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Microsoft .NET Framework 3.5 AND 4.6.2/4.7/4.7.1/4.7.2 on Windows 10 version 1607 2.0.50727.8987 AND 3.0.30729.8982 AND 4.7.4150.0; Microsoft .NET Framework 3.5 AND 4.6.2/4.7/4.7.1/4.7.2 on Windows Server 2016 2.0.50727.8987 AND 3.0.30729.8982 AND 4.7.4150.0; Microsoft .NET Framework 3.5 AND 4.6.2/4.7/4.7.1/4.7.2 on Windows Server 2019 2.0.50727.9073 AND 3.0.30729.9070 AND 4.7.4150.0.

Low priority for now. Upgrade to Microsoft .NET Framework 3.5 AND 4.6.2/4.7/4.7.1/4.7.2 on Windows 10 version 1607 2.0.50727.8987 AND 3.0.30729.8982 AND 4.7.4150.0; Microsoft .NET Framework 3.5 AND 4.6.2/4.7/4.7.1/4.7.2 on Windows Server 2016 2.0.50727.8987 AND 3.0.30729.8982 AND 4.7.4150.0; Microsoft .NET Framework 3.5 AND 4.6.2/4.7/4.7.1/4.7.2 on Windows Server 2019 2.0.50727.9073 AND 3.0.30729.9070 AND 4.7.4150.0 or later.
