Absolute Path Traversal
CVE-2026-32175
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. All versions from 8.0.0 prior to 8.0.27, 9.0.0 prior to 9.0.16 and 10.0.0 prior to 10.0.8 are affected.
