{"id":"CVE-2026-73301","aliases":["GHSA-4qcj-m5wp-jmf4"],"url":"https://o3.security/vulnerability/CVE-2026-73301","summary":"Budibase: Missing RBAC on GET /api/global/groups allows BASIC users to enumerate all tenant groups and role mappings","details":"Budibase is an open-source low-code platform. Prior to 3.39.25, the GET /api/global/groups endpoint in packages/worker/src/api/routes/global/groups.ts omitted auth.builderOrAdmin, allowing an authenticated BASIC role user to enumerate tenant groups, role mappings and user memberships, builder permissions, and default-group flags. The disclosure exposes the tenant access-control structure to users who are not builders or administrators. This issue is fixed in version 3.39.25.","published":"2026-08-12T18:08:07.998Z","modified":"2026-08-13T04:01:55.566599289Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"@budibase/server","fixedVersion":null}],"fix":{"url":"https://github.com/Budibase/budibase/commit/93db77846e68231ba655f180581c94503985421a","label":"Budibase/budibase@93db778"},"references":[{"type":"FIX","url":"https://github.com/Budibase/budibase/commit/93db77846e68231ba655f180581c94503985421a"},{"type":"FIX","url":"https://github.com/Budibase/budibase/pull/19109"},{"type":"WEB","url":"https://github.com/Budibase/budibase/releases/tag/3.39.25"},{"type":"ADVISORY","url":"https://github.com/Budibase/budibase/security/advisories/GHSA-4qcj-m5wp-jmf4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/73xxx/CVE-2026-73301.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-73301"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-13T04:01:55.566599289Z"}}
