Budibase before 3.41.3 Cross-Application Resource Injection via Missing Authorization

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Budibase versions before 3.41.3 contain a missing authorization vulnerability in the POST /api/resources/duplicate endpoint that allows authenticated builders to inject tables, automations, queries, and screens into any other application without holding any role in the destination workspace. Attackers can inject resources by specifying an arbitrary destination workspace ID in the request body, then trigger injected automations with outgoing webhooks to exfiltrate data from victim applications.
