CVE-2026-93762 PUBLISHED

Data deletion and attribute disclosure via field-name method injection in in-memory queries

Assigner: mongodb
Reserved: 18.09.2026 Published: 18.09.2026 Updated: 18.09.2026

Mongoid contains an unsafe reflection weakness in the query path used for embedded documents. An application that passes an externally supplied field name to certain in-memory query methods may allow an unauthenticated party to obtain unintended disclosure of stored document data and to permanently remove stored records.
