CVE-2026-46424 Details
Description
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user identity and permissions from this cache (TTL: 3600 seconds), a user whose admin, builder, or app-level roles have been revoked via the public API retains those privileges for up to 1 hour.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.
A vulnerability exists in Budibase versions prior to 3.38.2, specifically within the public API role unassignment endpoint. When user roles are revoked through this endpoint, the corresponding user cache entries in Redis are not updated. As a result, users can retain certain privileges, such as admin or builder roles, for up to one hour, until the cache expires. This issue arises because the bulk update process directly modifies user documents in CouchDB without invalidating the related Redis cache, which is used to manage user identity and permissions.
Users can update to Budibase version 3.38.2, where this vulnerability is fixed. Instructions for updating can be found in the Budibase release notes.
