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.

Incorrect validation of files loaded from a local untrusted directory may allow local privilege escalation if the underlying operating systems is Windows. This may result in the application executing arbitrary behaviour determined by the contents of untrusted files. This issue affects MongoDB Server v5.0 versions prior to 5.0.27, MongoDB Server v6.0 versions prior to 6.0.16, MongoDB Server v7.0 versions prior to 7.0.12, MongoDB Server v7.3 versions prior 7.3.3, MongoDB C Driver versions prior to 1.26.2 and MongoDB PHP Driver versions prior to 1.18.1.

Required Configuration:

Only environments with Windows as the underlying operating system is affected by this issue

Some MongoDB Drivers may erroneously publish events containing authentication-related data to a command listener configured by an application. The published events may contain security-sensitive data when specific authentication-related commands are executed.

Without due care, an application may inadvertently expose this sensitive information, e.g., by writing it to a log file. This issue only arises if an application enables the command listener feature (this is not enabled by default).

This issue affects the MongoDB C Driver 1.0.0 prior to 1.17.7, MongoDB PHP Driver 1.0.0 prior to 1.9.2, MongoDB Swift Driver 1.0.0 prior to 1.1.1, MongoDB Node.js Driver 3.6 prior to 3.6.10, MongoDB Node.js Driver 4.0 prior to 4.17.0 and MongoDB Node.js Driver 5.0 prior to 5.8.0. This issue also affects users of the MongoDB C++ Driver dependent on the C driver 1.0.0 prior to 1.17.7 (C++ driver prior to 3.7.0).
