SCA: security update for github.com/gruntwork-io/terragrunt (GHSA-8394-6f8r-whxg)

medium Tenable Cloud Security Plugin ID 446022

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Terragrunt is a flexible orchestration tool that allows Infrastructure as Code written in OpenTofu or
 Terraform to scale. Prior to 1.0.4, Terragrunt trusts paths decoded from a downloaded module's
 .terragrunt-module-manifest during fileManifest.Clean() in internal/util/file.go. A malicious or
 compromised external module can place absolute or traversal paths in the manifest, causing cleanup to
 delete files outside the module cache that are accessible to the Terragrunt process before OpenTofu or
 Terraform executes. This deletion-only primitive can remove local source code or configuration and disrupt
 CI/CD pipelines. This issue is fixed in version 1.0.4. (CVE-2026-45099)

Solution

Update the github.com/gruntwork-io/terragrunt library and its related packages to version 1.0.4 or later.
