{"cve":"CVE-2026-45099","nvd":{"published":"2026-08-21T21:16:59.403","modified":"2026-10-12T16:10:00.220","status":"Awaiting Analysis","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":null,"cwes":["CWE-22"],"references":["https://github.com/gruntwork-io/terragrunt/commit/3d6f10d6bccc851c6506a307a0b8675e0346e65e","https://github.com/gruntwork-io/terragrunt/pull/6032","https://github.com/gruntwork-io/terragrunt/releases/tag/v1.0.4","https://github.com/gruntwork-io/terragrunt/security/advisories/GHSA-8394-6f8r-whxg"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-45099","score":0.0054,"percentile":0.45156,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-8394-6f8r-whxg","url":"https://osv.dev/vulnerability/GHSA-8394-6f8r-whxg","summary":"Terragrunt: Arbitrary File Deletion via Malicious Module Manifest","modified":"2026-08-18T14:55:57.579259076Z","packages":[{"ecosystem":"Go","name":"github.com/gruntwork-io/terragrunt","purl":"pkg:golang/github.com/gruntwork-io/terragrunt","ranges":["<1.0.4"],"fixed":["1.0.4"]}]},{"id":"GO-2026-6241","url":"https://osv.dev/vulnerability/GO-2026-6241","summary":"Terragrunt: Arbitrary File Deletion via Malicious Module Manifest in github.com/gruntwork-io/terragrunt","modified":"2026-08-18T14:45:04.094247793Z","packages":[{"ecosystem":"Go","name":"github.com/gruntwork-io/terragrunt","purl":"pkg:golang/github.com/gruntwork-io/terragrunt","ranges":["<1.0.4"],"fixed":["1.0.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
