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user identity and permissions from this cache (TTL: 3600 seconds), a user whose admin, builder, or app-level roles have been revoked via the public API retains those privileges for up to 1 hour.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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N","score":4.2},"cwes":["CWE-269"],"references":["https://github.com/Budibase/budibase/releases/tag/3.38.2","https://github.com/Budibase/budibase/security/advisories/GHSA-6vp2-6r7m-2jvx","https://github.com/Budibase/budibase/security/advisories/GHSA-6vp2-6r7m-2jvx"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-46424","score":0.00163,"percentile":0.05489,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6vp2-6r7m-2jvx","url":"https://osv.dev/vulnerability/GHSA-6vp2-6r7m-2jvx","summary":"Budibase: Missing Cache Invalidation on Public API Role Unassignment Allows Revoked Users to Retain Privileges for Up to 1 Hour","modified":"2026-09-10T03:50:45.892361723Z","packages":[{"ecosystem":"npm","name":"@budibase/backend-core","purl":"pkg:npm/%40budibase/backend-core","ranges":["<3.38.2"],"fixed":["3.38.2"]}]}],"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).
