{"id":"CVE-2026-45716","aliases":["GHSA-c54j-xp92-wh28"],"url":"https://o3.security/vulnerability/CVE-2026-45716","summary":"Budibase: Builder-to-Admin Privilege Escalation via onboardUsers Endpoint Without SMTP Configuration","details":"Budibase is an open-source low-code platform. Prior to 3.38.1, the POST /api/global/users/onboard endpoint is protected by workspaceBuilderOrAdmin middleware, allowing any user with builder permissions to access it. When SMTP email is not configured (the default for self-hosted Budibase instances), this endpoint bypasses the admin-restricted invite flow and directly creates users via bulkCreate, accepting arbitrary admin and builder role assignments from the request body. A builder-level user can create a new global admin account and receive the generated password in the response, achieving full privilege escalation. This vulnerability is fixed in 3.38.1.","published":"2026-05-27T17:09:43.383Z","modified":"2026-08-12T03:51:36.893475269Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00261,"percentile":0.17866,"asOf":"2026-08-14"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@budibase/worker","fixedVersion":"3.38.1"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/Budibase/budibase/releases/tag/3.38.1"},{"type":"ADVISORY","url":"https://github.com/Budibase/budibase/security/advisories/GHSA-c54j-xp92-wh28"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45716.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45716"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:36.893475269Z"}}
