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.

gitoxide（Rust crate gix ≤ 0.72.0 和 gix-validate ≤ 0.10.0）存在一个路径遍历漏洞。gix-validate 中的子模块名称校验函数仅通过 检查 的首次出现，使得构造的名称（例如 ）能够绕过校验；此外，该校验在生产代码路径中从未被调用。结合 中的信任继承缺陷——父仓库的 （ ）被克隆且跳过了所有权验证——攻击者可以构造一个恶意的 文件，使得基于 gitoxide 构建的受害工具以完全信任读取任意 git 仓库的配置（包括嵌入的凭据），从而绕过安全目录保护。该漏洞已

Vulnerability Title
gitoxide before 0.82.0 Path Traversal via Submodule Name Validation Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
gitoxide (Rust crates gix <= 0.72.0 and gix-validate <= 0.10.0) contains a path traversal vulnerability. The submodule name validation function in gix-validate only checks the first occurrence of '..' via name.find(b".."), allowing crafted names such as 'a..b/../../../.git/' to bypass the check; additionally this validation is never invoked in production code paths. Combined with a trust inheritance flaw in Submodule::open(), where the parent repository's git_dir_trust (Trust::Full) is cloned and the ownership verification is skipped, an attacker can craft a malicious .gitmodules file so that a victim tool built on gitoxide reads arbitrary git repository configuration (including embedded credentials) with full trust, bypassing safe-directory protections. Fixed in gix 0.82.0 and gix-validate 0.11.1.
