MongoDB BI Connector: Unescaped Identifiers in SHOW CREATE Enable SQL Injection
CVE-2026-77586 Published on August 28, 2026
MongoDB Connector for BI Unescaped Object Names in Generated SHOW CREATE Output
In MongoDB Connector for BI, MongoDB object names such as collection, field, and index names are placed into the quoted identifiers of the DDL text returned by SHOW CREATE statements without escaping the identifier delimiter. A user with permission to write to a sampled MongoDB collection can choose a name that closes the quoted identifier early, so that additional SQL text becomes part of the generated output. If an operator or automated tool later replays that generated statement against a SQL server, the additional text is executed with the privileges of that session.
