Description
CVE-2026-116676 is a command injection vulnerability in Atlantis, a self-hosted Golang application for Terraform pull request automation. Versions from 0.4.0 up to but not including 0.47.1 allow authenticated contributors to inject arbitrary shell commands via the workspace name in atlantis.yaml. This occurs because the workspace value is passed unsafely to a shell command executed with sh -c. Exploitation can lead to arbitrary command execution with the privileges of the Atlantis service account, exposing sensitive credentials and resources. The issue is fixed in version 0.47.1.
