{"id":"DEBIAN-CVE-2026-82253","details":"gitoxide (Rust crates gix \u003c= 0.72.0 and gix-validate \u003c= 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.","modified":"2026-09-04T21:00:36.122949960Z","published":"2026-08-28T12:16:38.027Z","upstream":["CVE-2026-82253"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-82253"}],"affected":[{"package":{"name":"rust-gix","ecosystem":"Debian:13","purl":"pkg:deb/debian/rust-gix?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.69.1-1","0.69.1-2","0.73.0-1","0.73.0-2","0.73.0-3","0.73.0-4","0.83.0-1","0.83.0-2","0.86.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-82253.json"}},{"package":{"name":"rust-gix","ecosystem":"Debian:14","purl":"pkg:deb/debian/rust-gix?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.83.0-1"}]}],"versions":["0.69.1-1","0.69.1-2","0.73.0-1","0.73.0-2","0.73.0-3","0.73.0-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-82253.json"}},{"package":{"name":"rust-gix-validate","ecosystem":"Debian:13","purl":"pkg:deb/debian/rust-gix-validate?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.1-1","0.11.1-1","0.11.3-1","0.9.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-82253.json"}},{"package":{"name":"rust-gix-validate","ecosystem":"Debian:14","purl":"pkg:deb/debian/rust-gix-validate?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.1-1"}]}],"versions":["0.10.1-1","0.9.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-82253.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
