CVE-2026-82253 gitoxide before 0.82.0 Path Traversal via Submodule Name Validation Bypass

What is CVE-2026-82253?

CVE-2026-82253 is a high-severity path traversal vulnerability in GitoxideLabs gitoxide, published on 28 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official 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.

Weakness: CWE-22
