Summary
Cross-tenant database retargeting via dot/NUL injection in namespace strings in the PHP Driver
Details

The MongoDB client library for PHP does not sufficiently sanitize special elements in application-supplied namespace identifiers before using them to construct the target namespace for database operations. An application that incorporates untrusted text into these identifiers may have operations silently directed at a different storage location than the one the application intended.
