Title
gitoxide before 0.82.0 Path Traversal via Submodule Name Validation Bypass
Summary
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.
