CVE-2026-81525: CWE-943: Improper Neutralization of Special Elements in Data Query Logic in MongoDB PHP Driver
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.
