{"id":"CVE-2026-54445","state":"PUBLISHED","title":"Vantage6: Set admin user and password from environment or configuration","description":"vantage6 is an open-source infrastructure for privacy preserving analysis. Versions prior to 5.0.0 provide an initial user with username `root` and password `root`. This is not ideal because attackers know that almost all vantage6 servers have a user with username `root` that probably has admin rights, and the initial password is very weak and it is possible that administrators forget to reset it. Version 5.0.0 fixes the issue. As a workaround, it is possible to delete the `root` user after it has been used to create other users.","publishedAt":"2026-06-17T22:14:51.461Z","updatedAt":"2026-06-18T15:49:54.097Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["vantage6 vantage6"],"affected":[{"vendor":"vantage6","product":"vantage6","versions":[{"version":"< 5.0.0","status":"affected"}]}],"references":["https://github.com/vantage6/vantage6/security/advisories/GHSA-fgmc-2hqj-86v4","https://github.com/vantage6/vantage6/issues/1932","https://github.com/vantage6/vantage6/blob/main/docs/release_notes.rst#500"],"weaknesses":["CWE-204","CWE-1393"],"ingestedAt":"2026-10-29T20:12:24.861Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/54xxx/CVE-2026-54445.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-54445","state":"PUBLISHED","datePublished":"2026-06-17T22:14:51.461Z","dateUpdated":"2026-06-18T15:49:54.097Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-15T15:30:40.317Z"},"containers":{"cna":{"title":"Vantage6: Set admin user and password from environment or configuration","descriptions":[{"lang":"en","value":"vantage6 is an open-source infrastructure for privacy preserving analysis.
