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"}}]}}
