CVE-2026-81522

Cross-tenant database retargeting via dot/NUL injection in namespace strings in the C++ Driver PUBLISHED

Description (CNA)

A weakness in the MongoDB C++ Driver's handling of caller-supplied namespace identifiers allows special characters embedded in those identifiers. An application that builds a namespace identifier from untrusted input without validating it may therefore have its operation directed at a different target than intended. This can result in limited unauthorized read and write access to data belonging to another logical tenant of the affected application.
