What is CVE-2026-77184?
CVE-2026-77184 is a medium-severity SQL injection vulnerability in MongoDB BI Connector, published on 28 Aug 2026. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Official description
In MongoDB Connector for BI, the description text of a collection's JSON schema validator is incorporated into the comment text of the DDL returned by SHOW CREATE statements without complete escaping of backslash characters. A user with permission to modify a collection's schema validator, in deployments configured to build their SQL schema from those validators, can cause additional SQL text to be embedded in that 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.
Weakness: CWE-89
