Budibase before 3.40.0 Credential Exposure via STRING Fields
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
Budibase before 3.40.0 fails to redact datasource credentials stored in STRING typed fields, allowing authenticated users to read MongoDB connection strings and Firebase private keys in plaintext. Attackers with table read permissions can retrieve datasource configurations through the read API to obtain live backend database credentials and service account keys.
