CVE-2026-93764
Plaintext storage of encrypted fields via skipped embedded models in encryption schema generation
CVSS Score
6.5
EPSS Score
0.0%
EPSS Percentile
0th
Mongoid may omit encryption rules for fields declared on embedded models when generating the client-side field-level encryption schema. Applications that enable this feature can therefore store values intended to be encrypted in readable form, with no error or warning. A party with routine read access to the database, a backup, or the underlying data files may then see data that was meant to remain unreadable outside the application.
