MongoDB Mongoid: information disclosure
High7.1CVE-2026-93763 · Published Sep 18, 2026 · updated Sep 24, 2026
A protection mechanism failure in the object-document mapper's encryption configuration generation can cause fields that an application declared for client-side field-level encryption to be written and kept in cleartext, without any error or warning. A party holding ordinary read access to the database can then read values that were intended to be protected from that party. This may result in unintended disclosure of sensitive information.
