Overview

What is CVE-2026-71556?

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 repository containing a symlink can cause go-git to read from or write to files outside the intended working directory when the repository is cloned and its worktree operations are used.

Versions 5.19.2 and 6.0.0-alpha.5.
