What is CVE-2026-73618?

Budibase Server versions prior to 3.40.0 are susceptible to a NoSQL injection attack via the MongoDB query execution endpoint. This vulnerability arises due to improper sanitization of user-supplied parameters in JSON query templates, allowing attackers with query write permissions to inject JSON structural characters. Such an attack can enable unauthorized access to read, alter, or delete documents in the MongoDB database, ultimately compromising data integrity and security.
