CVE-2026-14869: CWE-918: Server-Side Request Forgery (SSRF) in HashiCorp Tooling
The terraform-mcp-server before version 1.1.0 is vulnerable to a server-side request forgery issue in the streamable-HTTP transport that may allow an unauthenticated remote client to redirect the server's Terraform API requests, and the server-side authorization token, to an attacker-controlled endpoint. This vulnerability, CVE-2026-14869, is fixed in terraform-mcp-server 1.1.0.
AI Analysis
Technical Summary
CVE-2026-14869 is a server-side request forgery (SSRF) vulnerability affecting terraform-mcp-server prior to version 1.1.0. The issue resides in the streamable-HTTP transport mechanism, which can be manipulated by an unauthenticated remote client to redirect legitimate Terraform API requests along with the server's authorization token to an attacker-controlled endpoint. This could allow an attacker to misuse the server's credentials and potentially access sensitive resources. The vulnerability has a CVSS v3.1 base score of 8.6, indicating high severity. The vulnerability is resolved in terraform-mcp-server version 1.1.0.
Potential Impact
An unauthenticated attacker can exploit this SSRF vulnerability to redirect server-side Terraform API requests and the associated authorization token to an endpoint under the attacker's control. This could lead to unauthorized access to sensitive data or services that the server is authorized to access. The vulnerability does not impact integrity or availability directly but compromises confidentiality through token exposure.
Mitigation Recommendations
Upgrade terraform-mcp-server to version 1.1.0 or later, where this SSRF vulnerability is fixed. No other official remediation or temporary workaround is indicated. Patch status is confirmed fixed in version 1.1.0.
