Hi,

The following vulnerability was published for rust-gix-fs.

CVE-2026-100419[0]:
| gitoxide gix-fs before 0.23.0 contains a path validation bypass
| vulnerability in the worktree checkout mechanism that allows
| attackers to escape the worktree directory via symlink manipulation.
| During forced checkout with overwrite_existing enabled, attackers
| can craft malicious repository trees where symlink entries replace
| validated directories, causing subsequent files to be written
| outside the worktree through the symlink for code execution or file
| manipulation.
