What is CVE-2026-9737?

A vulnerability exists within MongoDB that affects its query planning process. This issue arises during the handling of sort patterns in raw BSONObj form, where certain meta expression cases are not explicitly managed. As a result, this may lead to incorrect transformations during query execution, potentially causing invariant failures. Understanding this vulnerability is crucial for maintaining the integrity and reliability of database operations in affected MongoDB versions.
