Details

Ludvig Pedersen discovered that the System.Security.Cryptography.Xml library in .NET incorrectly handled certain XML inputs. An attacker could possibly use this issue to consume excessive resources, resulting in a denial of service. (CVE-2026-33116, CVE-2026-26171)

Ludvig Pedersen and Kevin Jones discovered that the System.Security.Cryptography.Xml library in .NET incorrectly handled certain XML inputs. An attacker could possibly use this issue to cause .NET to crash, resulting in a denial of service. (CVE-2026-32203)

Ludvig Pedersen discovered that the System.Net.Mail component in .NET incorrectly handled certain inputs. An attacker could possibly use this issue to perform a network spoofing attack. (CVE-2026-32178)

It was discovered that the Microsoft.AspNetCore.DataProtection library in .NET did not properly verify cryptographic signatures under certain conditions. A remote attacker could possibly use this issue to elevate privileges. (CVE-2026-40372)
