What the vulnerability does

01Description

Budibase is an open-source low-code platform. Prior to 3.35.3, the VectorDB configuration endpoint in Budibase accepts a host parameter that undergoes no validation against internal IP ranges, reserved hostnames, or URL schemes. Any authenticated user with builder-level access can supply an arbitrary host value such as 169.254.169.254 or localhost, causing the server to initiate outbound TCP connections to internal network addresses or cloud metadata endpoints on their behalf.This vulnerability is fixed in 3.35.3.
