An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-47358 in the wild and no public exploit code.\n\nAffected product: tenable Terrascan. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-47358/ (Markdown: https://insights.sbomify.com/CVE-2026-47358/index.md)","id":"CVE-2026-47358","markdown":"https://insights.sbomify.com/CVE-2026-47358/index.md","name":"CVE-2026-47358","record":{"aliases":["GHSA-8c33-whfw-95gh"],"analysis":{"component_type":"developer_tool","fix_type":"end_of_life","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"IaC security scanner","requires_auth":"none","summary":"Unauthenticated attackers can exploit SSRF in Terrascan server mode to read local files via uploaded IaC templates, requiring server mode deployment.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"terrascan","vendor":"tenable"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"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","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"},{"id":"CWE-73","name":"External Control of File Name or Path"},{"id":"CWE-610","name":"Externally Controlled Reference to a Resource in Another Sphere"}],"description":"Terrascan v1.18.3 and prior are vulnerable to Server-Side Request Forgery (SSRF) via external URL resolution in uploaded IaC templates when running in server mode. When Terrascan parses uploaded ARM templates or CloudFormation templates, it resolves external URLs referenced within those templates via hashicorp/go-getter with all default detectors enabled, including FileDetector. An unauthenticated remote attacker can upload an ARM template containing a templateLink.uri or parametersLink.uri field, or a CloudFormation template containing an AWS::CloudFormation::Stack TemplateURL field, pointing to an attacker-controlled URL. Terrascan will fetch the attacker-controlled URL server-side. Unlike SSRF via the remote scan endpoint, file:// URLs are directly usable without requiring an X-Terraform-Get redirect, enabling local file read. 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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Server-side request forgery in Terrascan","id":"CVE-2026-47358","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache CloudStack: OS Command Injection due to unsanitized mount command","id":"CVE-2026-47359"},"packages":[],"prev":{"headline":"Server-side request forgery in Terrascan","id":"CVE-2026-47357"},"products":["Terrascan"],"published":"2026-05-19","related":[{"cvss_score":9.3,"headline":"Server-side request forgery in Terrascan","id":"CVE-2026-47357","kev_date_added":null,"published":"2026-05-19"},{"cvss_score":8.7,"headline":"Server-side request forgery in Terrascan","id":"CVE-2026-47356","kev_date_added":null,"published":"2026-05-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-19","vendors":["tenable"]},"summary":"Unauthenticated attackers can exploit SSRF in Terrascan server mode to read local files via uploaded IaC templates, requiring server mode deployment.","url":"https://insights.sbomify.com/CVE-2026-47358/"}
