Submodule metadata injection via symlinked .gitmodules
Published Aug 28, 2026 · Updated Aug 29, 2026
Improper symlink handling in GitoxideLabs gitoxide 0.52.0 and earlier allows attackers to inject external bytes into submodule metadata. Repository::submodules() reads the worktree .gitmodules path with std::fs::read(), following a symlink without verifying that its target remains inside the worktree. A malicious repository must contain the symlink, and a consuming workflow must load its submodules; the demonstrated result is attacker-controlled name, path, and URL metadata, not direct code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
