Sources and claim methodology

Upstream source description

Budibase before 3.40.0 contains a NoSQL injection vulnerability in the MongoDB datasource integration where user-supplied parameters are enriched with handlebars using noEscaping: true and parsed without operator filtering. Attackers can inject MongoDB operators through query parameters to bypass per-user access controls, read arbitrary documents, execute JavaScript via $where operators, or modify collections through update and delete operations.
