Security readout for executives and security teams
Plain-English summary
Terraform Enterprise versions up to v202106-1 had an authorization flaw involving run tokens. A user or process able to use affected API requests could gain organization owner privileges. That level of access can affect infrastructure workflows and governance. HashiCorp states this was fixed in v202107-1.
Executive priority
Treat as high priority if Terraform Enterprise is used. Organization owner escalation can undermine control of infrastructure automation. Absence of known exploitation reduces emergency pressure, but affected systems should be upgraded promptly.
Technical view
The issue is improper authorization on a subset of Terraform Enterprise API requests executed with the run token. The documented impact is privilege escalation to organization owner. The provided sources do not include CVSS, CWE, detailed request scope, or proof-of-exploitation information.
Likely exposure
Exposure is limited to HashiCorp Terraform Enterprise releases up to v202106-1. Organizations not running Terraform Enterprise, or already on v202107-1 or later, are not indicated as affected by the supplied sources.
Exploitation context
The source bundle does not show CISA KEV listing or active exploitation. It only states that run-token API authorization failures could allow escalation to organization owner. No exploit maturity, prerequisites beyond run-token API context, or public exploit details are provided.
Researcher notes
Evidence is sparse. The public CVE text and HashiCorp advisory identify the impacted product range, run-token authorization context, impact, and fixed release. They do not provide CVSS scoring, affected CPEs, endpoint details, or exploitation status.
Mitigation direction
- Upgrade Terraform Enterprise to v202107-1 or later.
- Review the HashiCorp advisory for any deployment-specific guidance.
- Identify deployments still running versions up to v202106-1.
- Review organization owner membership for unexpected changes.
- Confirm run-token handling follows current HashiCorp operational guidance.
Validation and detection
- Check each Terraform Enterprise deployment version.
- Verify remediated deployments report v202107-1 or later.
- Review audit records for organization owner role changes.
- Confirm no unsupported Terraform Enterprise releases remain in production.
- Document exposure decisions for any unpatched legacy deployment.
