CVE-2026-93763

Silent plaintext persistence via unresolved callable database name in encryption schema map

Published Sep 18, 2026 CVSS 4.0 · 7.1 High EPSS < 1% KEV · Not listed
Description
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.
