CVE-2026-46424

4.2 mediumEPSS 0.2%

Medium (4.2). EPSS 0.2% chance of exploitation in the next 30 days. Fixed in @budibase/backend-core 3.38.2.

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user identity and permissions from this cache (TTL: 3600 seconds), a user whose admin, builder, or app-level roles have been revoked via the public API retains those privileges for up to 1 hour.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.
