    High [CVE-2026-71556] Arbitrary file read/write via symbolic link resolution

    CVE-2026-71556Source published Source updated

    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. This could result in information disclosure or arbitrary file modification. Exploitation requires the application to clone an attacker-controlled repository and then perform worktree operations against it; applications that only process trusted repositories are not exposed. Red Hat rates the impact of this flaw as…

    Mitigation guidance
    • To reduce the risk of exploitation, do not clone or run worktree operations (checkout, status, add) on Git repositories originating from untrusted or attacker-controllable sources using an affected version of go-git. The issue is resolved by updating to go-git 5.19.2 or 6.0.0-alpha.5 (or later).
