Summary

Microsoft .NET Framework 1.0 SP3, 1.1 SP1, and 2.0 SP1 does not properly validate .NET verifiable code, which allows remote attackers to obtain unintended access to stack memory, and execute arbitrary code, via (1) a crafted XAML browser application (XBAP), (2) a crafted ASP.NET application, or (3) a crafted .NET Framework application, aka "Microsoft .NET Framework Pointer Verification Vulnerability."

Exploit prediction

20.98% chance of exploitation in the next 30 days, higher than 97% of all scored CVEs (FIRST EPSS, 2026-11-08).

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
