Official description

gitoxide before 0.52.1 follows symlinks when reading the worktree .gitmodules file, allowing attackers to inject out-of-repository bytes into submodule metadata. Attackers can create a malicious repository with a symlinked .gitmodules pointing outside the repository tree, causing gitoxide to parse arbitrary external files as submodule configuration and expose attacker-controlled name, path, and url values.
