Summary
Budibase Server before 3.40.0 contains a NoSQL injection vulnerability in the MongoDB query execution endpoint where user-supplied parameters are interpolated into JSON query templates without proper sanitization of JSON metacharacters. Attackers with query write permission can inject JSON structural characters to alter MongoDB queries, bypassing filters to read, modify, or delete arbitrary documents.
Risk Assessment
An attacker could gain unauthorized access to data, modify or delete it, potentially leading to confidentiality, integrity, and availability breaches.
Recommendation
Upgrade Budibase Server to version 3.40.0 or later.
