CVE-2026-73617Public exploitNetwork attack vector

Authenticated NoSQL injection via unescaped query interpolation

Published Aug 13, 2026 · Updated Aug 13, 2026

NoSQL injection in Budibase Server before 3.40.0 allows remote authenticated users to read or alter MongoDB documents. The enrichContext function inserts parameter values into JSON query templates with escaping disabled, parses the result, and passes injected MongoDB operators to driver calls without filtering. A BASIC app role and an exposed saved MongoDB query are required; accessible collections can be dumped, modified, or deleted, and exposed $where queries execute database-side JavaScript.
