CVE-2026-81522 is fixed in mongo-cxx-driver on 1 platform by DEBIAN-CVE-2026-81522 (version 4.5.1-1), released September 3, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
