CVE-2026-48151: Budibase: Webhook schema endpoint authorization bypass allows unauthenticated mutation of webhook and automation schema

June 12, 2026

The webhook schema-building endpoint is registered under builderRoutes, but the generic authorization middleware skips authorization for all paths matching /api/webhooks/schema. As a result, an unauthenticated caller can update the body schema for a known webhook and mutate the corresponding automation trigger output schema.
