CVE-2026-47358 May 19, 15:53 CRITICAL Act Now

Server-Side Request Forgery in Tenable Terrascan v1.18.3 and prior allows unauthenticated remote attackers to coerce the server into fetching arbitrary URLs, including file:// URIs that enable local file disclosure. The flaw is triggered when Terrascan runs in server mode and parses uploaded ARM or CloudFormation templates whose templateLink.uri, parametersLink.uri, or AWS::CloudFormation::Stack TemplateURL fields point to attacker-controlled destinations. No public exploit identified at time of analysis, and because Terrascan was archived in August 2023, no patch will ever be released.

CVE-2026-47357 May 19, 15:53 CRITICAL Act Now

Server-Side Request Forgery in Tenable's Terrascan IaC scanner (versions 1.18.3 and prior) lets unauthenticated remote attackers read arbitrary local files and exfiltrate ~/.netrc credentials when the tool runs in server mode. Because Terrascan was archived in August 2023, no vendor patch will ever be released, and the daemon binds to 0.0.0.0 with no authentication by default. No public exploit identified at time of analysis, but the CVSS 4.0 score of 9.2 reflects trivial network-reachable abuse paired with significant confidentiality scope change.

CVE-2026-47356 May 19, 15:53 HIGH This Week

Server-Side Request Forgery in Terrascan up to v1.18.3 lets unauthenticated remote attackers coerce the scanner's HTTP client to POST full IaC scan results - along with an attacker-chosen Bearer token in the Authorization header - to any URL supplied via the webhook_url multipart parameter. Because Terrascan was archived by Tenable in August 2023, no vendor patch will be released, leaving every existing server-mode deployment permanently exposed. No public exploit identified at time of analysis and the CVE is not on CISA KEV, but the trivial exploit primitive (a single multipart POST) makes weaponization straightforward.
