Credential disclosure via incomplete datasource field redaction
Published Aug 13, 2026 · Updated Aug 13, 2026
Information disclosure in Budibase before 3.40.0 allows remote authenticated users to read stored datasource credentials through its API. The removeSecrets routine masks only PASSWORD and SENSITIVE_LONGFORM schema fields, leaving MongoDB connectionString and Firebase privateKey values typed as STRING untouched. Table-read permission and a datasource identifier suffice to retrieve live database credentials or a service-account private key from the single-datasource read endpoint.
