{"id":"CVE-2026-54054","state":"PUBLISHED","title":"Transmute has full-read SSRF in URL file import (POST /api/files/url) — no host/IP validation, follows redirects","description":"Transmute is a free, open-source, self-hosted file conversion and compression tool. Prior to version 1.3.0, Transmute's URL import endpoint, `POST /api/files/url`, is vulnerable to Server-Side Request Forgery (SSRF). The HTTP downloader used by this endpoint fetches user-supplied URLs with redirects enabled and does not validate whether the target resolves to a public, external address. As a result, an authenticated user (or guest user if they are enabled) may be able to cause the Transmute server to make HTTP requests to internal or cloud-local resources from the server's network position. Because downloaded content is stored and can later be retrieved through `GET /api/files/{id}`, this issue can result in full-read SSRF rather than blind SSRF. This is fixed in version 1.3.0.","publishedAt":"2026-09-10T21:52:18.866Z","updatedAt":"2026-09-11T16:35:35.491Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["transmute-app transmute"],"affected":[{"vendor":"transmute-app","product":"transmute","versions":[{"version":"< 1.3.0","status":"affected"}]}],"references":["https://github.com/transmute-app/transmute/security/advisories/GHSA-89m5-mvmx-7xrf","https://github.com/transmute-app/transmute/releases/tag/v1.3.0"],"weaknesses":["CWE-918"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/54xxx/CVE-2026-54054.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-54054","state":"PUBLISHED","datePublished":"2026-09-10T21:52:18.866Z","dateUpdated":"2026-09-11T16:35:35.491Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-11T18:24:35.096Z"},"containers":{"cna":{"title":"Transmute has full-read SSRF in URL file import (POST /api/files/url) — no host/IP validation, follows redirects","descriptions":[{"lang":"en","value":"Transmute is a free, open-source, self-hosted file conversion and compression tool.
