CVE-2026-64672

Read full description

Terragrunt is a flexible orchestration tool that allows Infrastructure as Code written in OpenTofu or Terraform to scale. Prior to 1.1.1, the terragrunt catalog command derives a predictable per-repository catalog clone root under the shared system temporary directory and follows a symlink already placed at that path. A local attacker who can write to the temporary directory and predict the cataloged repository can redirect cleanup and cloning outside the intended root, causing an existing repository-named directory to be deleted and replaced in the victim's security context. The attack requires the victim to run terragrunt catalog on a shared host while the symlink is present, and it is not remotely exploitable. This issue is fixed in version 1.1.1.

Evidence context and dated references

Reality is general threat/review priority, combining observed exploitation, CVSS severity and fresh EPSS. Evidence confidence is separate. This is not calibrated risk, a victim count or an asset-specific assessment. A range reflects missing numeric inputs. Published 4 days ago. Exploitation evidence usually takes weeks to show up: a low reality score can mean there is no data yet, not that the flaw is mild.
