{"cve":"CVE-2026-82253","nvd":{"published":"2026-08-28T12:16:38.027","modified":"2026-08-31T19:17:16.430","status":"Deferred","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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-22"],"references":["https://github.com/GitoxideLabs/gitoxide/security/advisories/GHSA-p3hw-mv63-rf9w","https://www.vulncheck.com/advisories/gitoxide-before-0.82.0-path-traversal-via-submodule-name-validation-bypass","https://github.com/GitoxideLabs/gitoxide/security/advisories/GHSA-p3hw-mv63-rf9w"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-82253","score":0.00657,"percentile":0.51438,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-p3hw-mv63-rf9w","url":"https://osv.dev/vulnerability/GHSA-p3hw-mv63-rf9w","summary":"gix's submodule name validation bypass + trust inheritance flaw enables path traversal and credential disclosure","modified":"2026-09-10T03:50:47.163131243Z","packages":[{"ecosystem":"crates.io","name":"gix","purl":"pkg:cargo/gix","ranges":["<0.83.0"],"fixed":["0.83.0"]},{"ecosystem":"crates.io","name":"gix-validate","purl":"pkg:cargo/gix-validate","ranges":["<0.11.1"],"fixed":["0.11.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
