{"id":"CVE-2026-46424","aliases":["GHSA-6vp2-6r7m-2jvx"],"url":"https://o3.security/vulnerability/CVE-2026-46424","summary":"Budibase: Missing Cache Invalidation on Public API Role Unassignment Allows Revoked Users to Retain Privileges for Up to 1 Hour","details":"Budibase is an open-source low-code platform. Prior to 3.38.2, the public API role unassignment endpoint (POST /api/public/v1/roles/unassign) updates user documents in CouchDB but does not invalidate the corresponding Redis user cache entries. Because the authentication middleware resolves user identity and permissions from this cache (TTL: 3600 seconds), a user whose admin, builder, or app-level roles have been revoked via the public API retains those privileges for up to 1 hour. This vulnerability is fixed in 3.38.2.","published":"2026-05-27T17:05:21.894Z","modified":"2026-08-12T03:51:23.791159059Z","cvss":{"score":4.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N"},"epss":{"score":0.00163,"percentile":0.05979,"asOf":"2026-08-14"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@budibase/backend-core","fixedVersion":"3.38.2"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/Budibase/budibase/releases/tag/3.38.2"},{"type":"ADVISORY","url":"https://github.com/Budibase/budibase/security/advisories/GHSA-6vp2-6r7m-2jvx"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46424.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46424"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:23.791159059Z"}}
