# Terragrunt catalog predictable temp symlink clobber in github.com/gruntwork-io/terragrunt

Terragrunt's catalog feature creates a temporary symlink at a predictable path, so a local user on the same machine could pre-create that path and make Terragrunt overwrite or clobber a file of their choosing. The sources do not give the exact impact beyond that.

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

## Affected

- go:github.com/gruntwork-io/terragrunt affected < 1.1.1 fixed 1.1.1

## How to check

Run terragrunt --version and check whether it is older than 1.1.1.

## Fix

Upgrade github.com/gruntwork-io/terragrunt to 1.1.1 or later.

## Timeline
