CVE-2023-34236

Weave GitOps Terraform Controller (aka Weave TF-controller) is a controller for Flux to reconcile Terraform resources in a GitOps way. A vulnerability has been identified in Weave GitOps Terraform Controller which could allow an authenticated remote attacker to view sensitive information. This vulnerability stems from Weave GitOps Terraform Runners (tf-runner), where sensitive data is inadvertently printed - potentially revealing sensitive user data in their pod logs. In particular, functions tfexec.ShowPlan, tfexec.ShowPlanRaw, and tfexec.Output are implicated when the tfexec object set its Stdout and Stderr to be os.Stdout and os.Stderr. An unauthorized remote attacker could exploit this vulnerability by accessing these prints of sensitive information, which may contain configurations or tokens that could be used to gain unauthorized control or access to resources managed by the Terraform controller. A successful exploit could allow the attacker to utilize this sens
