go-git: Worktree operations may follow symlinks
CVE-2026-71556 is fixed in 6 products on 1 platform, first by RHSA-2026:68335, released August 13, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
