CVE-2026-81525 (GCVE-0-2026-81525)

Vulnerability from cvelistv5 – Published: 2026-08-27 18:32 – Updated: 2026-08-28 15:49

Title

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

Summary

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.
