Title

Unicode normalization mismatch in go-slug ignore pattern matching may bypass intended file exclusions

Summary

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.

Severity

5.5 (Medium)
