CVE-2026-42899 Scheduled assessment ASP.NET Core Denial of Service Vulnerability A flaw was found in dotnet. An infinite loop in ASP.NET Core allows an unauthenticated remote attacker to cause a denial of service over a network. This issue can lead to an application crash and a high consumption of system resources.	7.5 · CVSS 3.1 · HighSource: CNA	No confirmation recordedNo CISA KEV match was present at the last successful refresh.

CVE-2026-32175 Scheduled assessment .NET Core Tampering Vulnerability A tampering vulnerability exists when .NET Core improperly handles specially crafted files. An attacker who successfully exploited this vulnerability could write arbitrary files and directories to certain locations on a vulnerable system. However, an attacker would have limited control over the destination of the files and directories. To exploit the vulnerability, an attacker must send a specially crafted file to a	4.3 · CVSS 3.1 · MediumSource: CNA	No confirmation recordedNo CISA KEV match was present at the last successful refresh.
