Upgrade github.com/hashicorp/go-slug/internal/ignorefiles to version 0.18.3 or higher.
Overview
Affected versions of this package are vulnerable to Path Equivalence in its .terraformignore pattern matching, which compares filenames against ignore patterns without normalizing both to a common Unicode form. An attacker with write access to the working directory can cause sensitive files to be included in a Terraform slug upload despite an exclusion rule that should match them, by naming a file in a Unicode form that differs from the form used in the pattern. This requires local access to the working directory and a filename and pattern that differ only by Unicode normalization, which arises primarily on macOS filesystems.
