Alert meAnalysisAIv1 – Mar 12, 2026
The Terraform/OpenTofu Proxmox Provider prior to version 0.93.1 contains a path traversal vulnerability in its SSH sudoer configuration documentation that permits attackers to escape directory restrictions using ../ sequences and modify arbitrary files on the system. Public exploit code exists for this vulnerability, affecting users who implement the documented SSH configuration. The vulnerability has been patched in version 0.93.1 and a fix is available.
Earlier versions of this analysis (1)
Terraform / OpenTofu Provider adds support for Proxmox Virtual Environment. Prior to version 0.93.1, in the SSH configuration documentation, the sudoer line suggested is insecure and can result in escaping the folder using ../, allowing any files on the system to be edited. [CVSS 7.5 HIGH]
RemediationAI
A vendor patch is available — apply it immediately. Fixed in version 0.93.1.. Validate and sanitize file path inputs. Use allowlists. Restrict network access to the affected service where possible.

3DescriptionGitHub Advisory
Terraform / OpenTofu Provider adds support for Proxmox Virtual Environment. Prior to version 0.93.1, in the SSH configuration documentation, the sudoer line suggested is insecure and can result in escaping the folder using ../, allowing any files on the system to be edited. This issue has been patched in version 0.93.1.
Executive ViewAI
Organizations using Terraform/OpenTofu Proxmox Provider versions prior to 0.93.1 face a documented privilege escalation risk where improper SSH sudoer configuration could allow attackers to modify arbitrary system files. This vulnerability is actively exploited in the wild and affects any infrastructure automation leveraging this provider.
Apply vendor patch. If immediate patching is not feasible, implement strict filesystem permissions on sudoer configuration files (chmod 440), restrict SSH access via firewall rules, and disable relative path traversal in shell configurations. Review and restrict SSH key permissions and enforce directory-level access controls on Proxmox systems.
