- Severity: medium (CVSS 6.5 v3.1)
- Exploited in the wild: not listed in CISA KEV

- Public exploit or detection template: none known
- Published: 2026-09-18 · updated 2026-09-24
- Weakness: CWE-312
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.
