Description

Budibase before 3.40.0 contains server-side request forgery vulnerabilities in OpenAPI query import and REST query execution that allow authenticated builder-level users to bypass DNS pinning protections through DNS rebinding attacks. Attackers can configure hostnames that resolve to public addresses during validation but resolve to loopback or private addresses during actual connection, allowing access to blocked internal HTTP services.
