An authenticated user can submit a request whose input is treated as a URL by the server and used to issue an outbound HTTP GET request without URL validation or destination filtering. The response body is then returned to the user.\n\n\n\n\nThis allows an authenticated attacker to reach internal services and metadata endpoints that would not otherwise be accessible from the public network, and to retrieve their contents. The impact is information disclosure and internal infrastructure reconnaissance; the request primitive is limited to HTTP GET with no custom headers. Altium Enterprise Server is fixed in 8.1.1; the issue has been remediated in Altium 365 at the service level.","publishedAt":"2026-06-05T20:51:28.935Z","updatedAt":"2026-06-08T13:11:23.796Z","severity":{"score":8.3,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","source":"Altium"},"assigner":"Altium","products":["Altium Altium Enterprise Server","Altium Altium 365"],"affected":[{"vendor":"Altium","product":"Altium Enterprise Server","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"8.1.1","versionType":"semver"}],"platforms":["Web"],"modules":["Platform Design (GraphQL FileDownloadService)"]},{"vendor":"Altium","product":"Altium 365","defaultStatus":"affected","versions":[{"version":"unspecified","status":"affected"}],"platforms":["Web"],"modules":["Platform Design (GraphQL FileDownloadService)"]}],"references":["https://www.altium.com/platform/security-compliance/security-advisories"],"weaknesses":["CWE-918","CWE-200"],"ingestedAt":"2026-10-29T20:10:52.580Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/11xxx/CVE-2026-11424.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-11424","state":"PUBLISHED","datePublished":"2026-06-05T20:51:28.935Z","dateUpdated":"2026-06-08T13:11:23.796Z","assignerShortName":"Altium","assignerOrgId":"4760f414-e1ae-4ff1-bdad-c7a9c3538b79","dateReserved":"2026-06-05T20:20:57.336Z"},"containers":{"cna":{"title":"Server-Side Request Forgery in Altium Platform Design GraphQL Service Allows Information Disclosure","descriptions":[{"lang":"en","value":"A server-side request forgery (SSRF) vulnerability exists in a GraphQL service component shared by Altium Enterprise Server and Altium 365.
