Vulnerability from github – Published: 2026-08-28 12:30 – Updated: 2026-08-28 12:30

Details

gix-worktree-state before 0.33.0 (part of gitoxide) allows writing files outside the worktree on Windows. gix_worktree_state::checkout() follows an existing terminal symlink during non-exclusive (incremental) materialization (destination_is_initially_empty: false) when core.symlinks is true. If a symlink entry (mode 120000) is first checked out at a path P pointing outside the worktree, a subsequent incremental checkout of a regular-file entry (mode 100644) at the same path follows the existing reparse point and writes the blob content through the link, overwriting files outside the worktree.

Severity
