Summary

Parse Server before 8.6.111 and from 9.0.0 before 9.10.6-alpha.3 on MongoDB skips field type validation for null-valued dot notation keys. This flaw, classified as CWE-20, lets sub-documents be written beneath Pointer, Number, String, Date, or Boolean fields. Any client with write access, including unauthenticated clients where public writes are permitted, can corrupt field values, make objects unreadable through internal date fields, or break atomic operations on number fields.
