An unauthenticated remote attacker can supply an attacker-controlled HTTP URL as remote_url with remote_type set to \"http\". The URL is passed directly to hashicorp/go-getter (v1.7.5) without validation. Go-getter's HttpGetter supports the X-Terraform-Get response header, allowing the attacker's server to redirect the download to a file:// URL, enabling local file read. Additionally, HttpGetter has Netrc set to true, causing it to read ~/.netrc and send stored credentials to attacker-controlled hostnames. This affects deployments running terrascan in server mode (terrascan server), which binds to 0.0.0.0 with no authentication. Note: Terrascan was archived in August 2023 and no patch will be released." } ], "metrics": [ { "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ], "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N", "baseScore": 7.5, "baseSeverity": "HIGH" } }, { "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ], "cvssV4_0": { "version": "4.0", "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N", "baseScore": 9.3, "baseSeverity": "CRITICAL" } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-918", "description": "Server-Side Request Forgery (SSRF)" } ] }, { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-610", "description": "Externally Controlled Reference to a Resource in Another Sphere" } ] }, { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-73", "description": "External Control of File Name or Path" } ] } ], "references": [ { "url": "https://github.com/tenable/terrascan", "name": "Terrascan GitHub Repository" } ], "providerMetadata": { "orgId": "5ac1ecc2-367a-4d16-a0b2-35d495ddd0be", "shortName": "tenable", "dateUpdated": "2026-05-19T15:53:05.222Z" }, "credits": [ { "lang": "en", "value": "Tristan Madani (@TristanInSec) from Talence Security", "type": "finder" } ], "x_generator": { "engine": "cvelib 1.8.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-05-19T17:09:02.885966Z", "id": "CVE-2026-47357", "options": [ { "Exploitation": "none" }, { "Automatable": "yes" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-05-19T17:09:32.072Z" } } ] } }
