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.
AnalysisAI
Path traversal and trust inheritance flaws in gitoxide's Rust crates gix (≤ 0.72.0) and gix-validate (≤ 0.10.0) allow an attacker who supplies a malicious repository to read arbitrary git configuration files - including embedded credentials - from a victim system. The attack chains three bugs: a first-occurrence-only find(b"..") check in submodule name validation that is bypassed by names like a..b/../../../.git/, the fact that this validation function is never invoked in production code, and a trust inheritance flaw in Submodule::open() that propagates the parent repository's Trust::Full to the traversed path while skipping ownership verification entirely. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must be running a tool built on the `gix` crate (< 0.83.0 per GHSA) that processes git repositories with submodule entries - specifically, code paths that call `Submodule::open()` or construct paths via `git_dir()` from submodule names. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 8.7 with vector AV:N/AC:L/AT:N/PR:N/UI:N/VC:H reflects high real-world confidentiality impact: no authentication is required on the attacker side, attack complexity is low, and the confidentiality impact on the vulnerable system is high due to potential credential disclosure from git configs. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade gix to 0.83.0 and gix-validate to 0.11.1 per the GHSA advisory at https://github.com/GitoxideLabs/gitoxide/security/advisories/GHSA-p3hw-mv63-rf9w. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Audit systems running gix ≤0.72.0 or gix-validate ≤0.10.0; identify any committed or cached credentials within git configuration files; initiate credential rotation for all Git-related access tokens and API keys. …
