CVE-2026-71556 go-git: Worktree operations may follow symlinks

go-git is an extensible git implementation library written in pure Go. Prior to 5.19.2 and 6.0.0-alpha.5, worktree operations including checkout, status, and add resolve symbolic links inside the working tree without confining resolution to the worktree boundary, so a maliciously crafted reposito...

CVE-2026-71556

CVE-2026-71556 affects the Go library go-git (Go) and involves worktree operations (checkout, status, add) not confining symlink resolution to the worktree boundary.
