CVE-2026-81522

Name of the Vulnerable Software and Affected Versions MongoDB C++ Driver (affected versions not specified)

Description A weakness in the handling of caller-supplied namespace identifiers allows the embedding of special characters. If an application constructs a namespace identifier using untrusted input without proper validation, operations may be redirected to an unintended target. This can lead to limited unauthorized read and write access to data belonging to another logical tenant within the application.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
