CVE-2026-54351 is a high-severity mass assignment vulnerability in Budibase affecting versions prior to 3.39.9. The flaw is in the publicly accessible webhook trigger handling, specifically the externalTrigger() path, where the full HTTP request body is incorporated into automation execution parameters without adequately protecting internal fields. By supplying an appId value in the webhook POST body, an attacker can overwrite the internal appId property that should identify the correct workspace context. In the default asynchronous processing path used for webhook automations without a collect step, the queued worker subsequently executes the attacker-selected automation in the context of a victim workspace rather than the attacker’s own workspace. This breaks workspace isolation and can expose the victim workspace’s data and automation context.
