Improper Preservation of Permissions in gix-worktree-state - CVE-2025-22620

Detailed vulnerability description

The vulnerability allows a local user to modify executable files with overly permissive world-writable permissions.

The vulnerability exists due to improper preservation of permissions in gix_worktree_state::checkout and checkout::entry::finalize_entry when checking out executable files with destination_is_initially_empty set to false. A local user can perform a checkout that sets mode 0777 on executable files to modify executable files with overly permissive world-writable permissions.

This affects Unix-like systems, and user interaction is required to perform the checkout operation.
