No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

HashiCorp go-slug 0.4.0 through 0.18.2 could allow a local attacker to bypass .terraformignore exclusions and cause sensitive files to be included in Terraform slug uploads due to improper handling of Unicode normalization during path matching.
