CVE-2026-71556: Go-Git

High severity, CVSS 7.1. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Go-Git Go-Git: before 5.19.2 (fixed in 5.19.2); from 6.0.0-alpha.1, before 6.0.0-alpha.5 (fixed in 6.0.0-alpha.5)
