CVE-2026-32203 Scheduled assessment .NET and Visual Studio Denial of Service Vulnerability A flaw was found in .NET. A remote attacker could exploit a stack overflow vulnerability during encrypted key nested decryption, leading to a Denial of Service (DoS). This could make the affected system unavailable to legitimate users.	7.5 · CVSS 3.1 · HighSource: CNA	No confirmation recordedNo CISA KEV match was present at the last successful refresh.

CVE-2026-33116 Scheduled assessment .NET, .NET Framework, and Visual Studio Denial of Service Vulnerability A flaw was found in .NET. A remote attacker could exploit this vulnerability by crafting a malicious XML document that triggers an infinite recursion within the XmlDecryptionTransform component.

CVE-2026-32178 Scheduled assessment .NET Spoofing Vulnerability A flaw was found in the .NET runtime (System.Net.Mail) in how email address data is parsed. Improper neutralization of special characters, specifically carriage return and line feed (CR/LF) sequences, may allow specially crafted email address input to be interpreted incorrectly. An attacker could exploit this issue to perform email spoofing by injecting additional headers or altering how the email address is processe	7.5 · CVSS 3.1 · HighSource: CNA	No confirmation recordedNo CISA KEV match was present at the last successful refresh.
