An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-45099 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/gruntwork-io/terragrunt (Go): affected all versions; fixed in 1.0.4\n- github.com/gruntwork-io/terragrunt (Go): affected all versions; fixed in 1.0.4\n- github.com/gruntwork-io/terragrunt (Go): affected all versions; fixed in 1.0.4\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-45099/ (Markdown: https://insights.sbomify.com/CVE-2026-45099/index.md)","id":"CVE-2026-45099","markdown":"https://insights.sbomify.com/CVE-2026-45099/index.md","name":"CVE-2026-45099","record":{"aliases":["GHSA-8394-6f8r-whxg","GO-2026-6241","MINI-hrq6-h952-wpqg","MINI-pv3f-2886-3ghh"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Infrastructure as Code tool","requires_auth":"none","summary":"A malicious module manifest allows arbitrary file deletion outside the cache, disrupting CI/CD pipelines and removing local source code.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"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.
