# Wish Go library: git middleware path traversal lets SSH users reach other repos

Link for people: https://infrastack.ai/live/CVE-2026-53980 (this .md is for agents)

Charmbracelet wish, a Go library for building SSH servers, has a path traversal flaw in its git middleware. An authenticated SSH user can supply crafted repository paths to read or write Git repositories outside the configured root directory.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the version of `charm.land/wish/v2` in `go.mod` or `go list -m charm.land/wish/v2`
- Look for `git.Middleware()` usage in your Go SSH server code

## Fix

- `charm.land/wish/v2` before `2.0.5`: move to `2.0.5` or later

## Timeline

## Documents

- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/charmbracelet-wish-path-traversal-via-git-middleware
- [fix] Patch: github.com https://github.com/charmbracelet/wish/commit/533db0daa90446b0d4ae3284877179c37e0cc48e
- [fix] Release notes: github.com https://github.com/charmbracelet/wish/releases/tag/v2.0.5

## From the sources

Charmbracelet wish before 2.0.5 contains a path traversal vulnerability in the git middleware (charm.land/wish/v2) that allows authenticated SSH users to escape the configured repository directory by supplying crafted repo paths that bypass a flawed forward-slash-count containment check in git.Middleware(). Attackers can use a single-depth path ../evil, or on Windows a payload ..\..\evil that defeats the slash-count guard entirely, to read or write arbitrary repositories outside the intended root via git-upload-pack, git-upload-archive, or git-receive-pack.
