AI-suggested
Upgrade Budibase Server to version 3.45.0 or later, where this vulnerability is fixed by properly redacting sensitive datasource credentials before broadcasting updates. Until the upgrade is applied, restrict Builder access to trusted users only to minimize risk.
Description
CVE-2026-100687 is a vulnerability in Budibase Server versions before 3.45.0 where plaintext datasource credentials are exposed to unauthorized actors. This occurs because the server fails to redact sensitive information such as database passwords and API keys before broadcasting external table updates to the Builder collaboration websocket room. Attackers with Builder access can intercept these unredacted credentials during table save or delete operations.
