CVE-2026-32175 (GCVE-0-2026-32175)
Vulnerability from nvd – Published: 2026-05-12 16:59 – Updated: 2026-06-19 16:12

Title
.NET Core Tampering Vulnerability
Summary
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 vulnerable system.
The security update fixes the vulnerability by ensuring .NET Core properly handles files.

CVE-2026-32175 (GCVE-0-2026-32175)

Title
.NET Core Tampering Vulnerability
Summary
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 vulnerable system.
The security update fixes the vulnerability by ensuring .NET Core properly handles files.
