    Terragrunt catalog predictable temp symlink clobber

    CVE-2026-64672 · GHSA-wv6g-x823-wx9m

    Affected
    • Go github.com/gruntwork-io/terragrunt < 1.1.1
    Fixed in
    1.1.1· Vendor fix available
    Issue
    Terragrunt's terragrunt catalog command clones each repository referenced in your catalog configuration into a temporary working directory. In affected versions, the clone path it derived was deterministic and sat under the shared system temporary directory, in the form <tmp/catalog-<base64 sha1 of the repo URL. Because that path was predictable and Terragrunt followed a symlink already present there instead of rejecting it, a local attacker could plant a symlink at that path and cause Terragrunt to delete a directory and re-clone into it outside the intended temporary root. Impact This affected users who ran terragrunt catalog on a host they shared with other local users or processes they did not fully trust, such as a multi-user server or a shared CI runner. The attack required a local attacker: a separate local user or process able to write to the shared system temporary directory. It was not remotely exploitable, and the victim had to run terragrunt catalog while the…

    Recommended action: Upgrade to 1.1.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.

    Terragrunt: Arbitrary File Deletion via Malicious Module Manifest

    CVE-2026-45099 · GHSA-8394-6f8r-whxg

    Affected
    • Go github.com/gruntwork-io/terragrunt < 1.0.4
    Fixed in
    1.0.4· Vendor fix available
    Issue
    Terragrunt is vulnerable to an arbitrary file deletion flaw when downloading external modules. If a remote module contains a maliciously crafted .terragrunt-module-manifest file, Terragrunt can be tricked into deleting files anywhere on the local filesystem that the Terragrunt process has access to. Impact This vulnerability impacts users who download and run untrusted or compromised OpenTofu/Terraform modules. The file deletion occurs during the module download and initialization phase, meaning it happens before OpenTofu or Terraform executes. In a CI/CD environment or automated runner, an attacker-controlled module could delete arbitrary files, causing denial of service in the deployment pipeline. In a local environment, it could lead to the loss of local source code or configuration files. This vulnerability is a deletion-only primitive; it does not directly allow for arbitrary code execution (RCE) or data exfiltration. Affected Versions - Terragrunt < v1.0.4 Patches This…
