{"id":"CVE-2026-54054","summary":"Transmute has full-read SSRF in URL file import (POST /api/files/url) — no host/IP validation, follows redirects","details":"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.","aliases":["GHSA-89m5-mvmx-7xrf"],"modified":"2026-09-12T03:46:44.559038382Z","published":"2026-09-10T21:52:18.866Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54054.json"},"references":[{"type":"WEB","url":"https://github.com/transmute-app/transmute/releases/tag/v1.3.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54054.json"},{"type":"ADVISORY","url":"https://github.com/transmute-app/transmute/security/advisories/GHSA-89m5-mvmx-7xrf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54054"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/transmute-app/transmute","events":[{"introduced":"0"},{"fixed":"be1698c2cb7a61fccbd47d630e49f2aa55e8c2a9"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.3.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v1.2.0","v1.2","v1.1.0","v1.1","v1.0.0","v1.0","v0.12.2","v0.12","v0","v0.12.1","v0.12.0","v0.10.1","v0.10","v0.10.0","v0.9.0","v0.9","v0.8.0","v0.8","v0.7.0","v0.7","v0.6.1","v0.6","v0.6.0","v0.5.0","v0.5","v0.4.5","v0.4","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.1","v0.3","v0.3.0","v0.2.0","v0.2","v0.1.2","v0.1","v0.1.1","v0.1.0","v0.0.1","v0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54054.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
