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

Quick assessment

Affected
GitoxideLabs gitoxide
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 0.24.1 版本之前的 gitoxide 项目中的 gix-fs 组件存在凭据泄露漏洞。远程攻击者可通过在特制的仓库中提供 UNC 符号链接目标，从而捕获 NTLM 凭据。当受害者在启用符号链接功能的 Windows 系统上检出该仓库时，gix_fs::symlink::create 函数会对 UNC 目标调用 is_dir()，进而触发 SMB 身份验证，导致用户名、域以及 NTLMv2 哈希值被泄露。

Vulnerability Title
gix-fs before 0.24.1 NTLM Credential Disclosure via Windows Symlink UNC Probe
Source: CVE Program / CVE List V5
Vulnerability Description
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.
