# CVE-2026-123532: gix-fs before 0.24.1 NTLM Credential Disclosure via Windows Symlink UNC Probe

Status: published. Published: 2026-11-08. Updated: 2026-11-12.

gix-fs in gitoxide before 0.24.1 contains a credential disclosure vulnerability that allows remote attackers to capture NTLM credentials by supplying UNC symlink targets in a crafted repository. When a victim checks out the repository on Windows with symlinks enabled, gix_fs::symlink::create calls is_dir() on the UNC target, triggering SMB authentication that leaks the username, domain, and NTLMv2 hash.
