What is CVE-2026-82242?

Budibase versions prior to 3.41.3 possess a missing authorization flaw in the POST /api/resources/duplicate endpoint. This vulnerability allows authenticated users with the role of builders to inject various resources, such as tables, automations, queries, and screens, into any designated workspace. By specifying an arbitrary workspace ID in their requests, attackers can exploit this flaw to transfer unauthorized resources across applications and may use outgoing webhooks to trigger these resources, leading to potential data exfiltration.
