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.","published":"2026-08-28T12:16:38.027","modified":"2026-08-28T12:16:38.027","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/GitoxideLabs/gitoxide/security/advisories/GHSA-p3hw-mv63-rf9w"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/gitoxide-before-0.82.0-path-traversal-via-submodule-name-validation-bypass"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-28T12:16:38.027"}}
