CVE-2026-82248Public exploitNetwork attack vector

Arbitrary file overwrite via terminal symlink following

Published Aug 28, 2026 · Updated Aug 28, 2026

Link following in gitoxide gix-worktree-state before 0.33.0 allows remote attackers to overwrite files outside a Windows worktree. During incremental checkout, checkout() skips a terminal-component collision check and opens a regular-file path through an existing reparse point. Exploitation requires user interaction, core.symlinks enabled, and a downstream application using the non-empty-destination library path; shipped CLI call sites are not reachable.
