7.1 highCVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:LCVE-2026-71556
High (7.1). EPSS 0.4% chance of exploitation in the next 30 days. Fixed in github.com/go-git/go-git/v5 5.19.2.
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.
