{"cve":"CVE-2026-48150","nvd":{"published":"2026-05-27T18:16:27.463","modified":"2026-06-17T10:54:53.820","status":"Deferred","description":"Budibase is an open-source low-code platform. Prior to 3.39.0, /api/public/v1/roles/assign is guarded by the builderOrAdmin middleware, which passes any user who is a builder for the app id in the x-budibase-app-id header. That check admits both global builders and workspace-scoped builders (builder.apps set but builder.global unset). The controller then spreads the request body into the SDK call, and the SDK grants builder.global=true or admin.global=true on whichever user ids the caller supplies. Bob, a workspace-scoped builder with an API key, promotes himself or any other user to global admin with one POST. The whole flow is tenant-wide privilege escalation from an app-level role, available to anyone with an Enterprise license that unlocks the EXPANDED_PUBLIC_API feature. This vulnerability is fixed in 3.39.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:L","score":9.0},"cwes":["CWE-915"],"references":["https://github.com/Budibase/budibase/security/advisories/GHSA-6xp4-cf37-ppjh","https://github.com/Budibase/budibase/security/advisories/GHSA-6xp4-cf37-ppjh"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-48150","score":0.00292,"percentile":0.21865,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6xp4-cf37-ppjh","url":"https://osv.dev/vulnerability/GHSA-6xp4-cf37-ppjh","summary":"Budibase: Workspace-scoped builder escalates to global admin via /api/public/v1/roles/assign","modified":"2026-09-10T03:50:48.682601809Z","packages":[{"ecosystem":"npm","name":"@budibase/server","purl":"pkg:npm/%40budibase/server","ranges":["<3.39.0"],"fixed":["3.39.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
