Detailsinfo

A vulnerability was found in MongoDB C# Driver up to 3.12.x. It has been rated as problematic. Affected by this issue is an unknown functionality of the component Update-Statement Construction. The manipulation with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. Impacted is integrity. CVE summarizes:

A data-query-logic neutralization weakness in the update-statement construction component of the MongoDB C# Driver can cause application-supplied values to be interpreted as query/update logic rather than as literal data. An application user who can influence the content of values that the application passes into the affected builder surface, without any special privilege beyond ordinary read-write application access, may cause stored data to be modified or removed in ways the application never intended. The result is unauthorized integrity impact on the affected application data; there is no direct loss of confidentiality or availability of the database service.

The advisory is shared for download at jira.mongodb.org. This vulnerability is handled as CVE-2026-114652 since 10/21/2026. The exploitation is known to be easy. The attack may be launched remotely.
