CVE-2026-92756 MongoDB Inc. CVE debrief

CVE-2026-92756 debrief based on MongoDB Entity Framework Core Provider CVE description. Applications built on MongoDB Entity Framework Core Provider may store protected fields unencrypted due to combined encryption settings. This vulnerability affects applications that use both independent encryption settings and the provider's encryption settings, potentially leading to silent loss of TLS and schema-map settings. As a result, protected fields might be stored unencrypted in the database, exposing sensitive data.

Who should care

Developers and administrators using MongoDB Entity Framework Core Provider should assess encryption configurations and verify schema-map settings to prevent data exposure. They should review the current encryption setup, ensure consistent encryption settings, and implement compensating controls for exposed systems while remediation is scheduled and verified.

Why it matters

CVE-2026-92756 affects MongoDB Entity Framework Core Provider, potentially leading to unencrypted storage of protected fields. Developers and administrators should assess encryption configurations and verify schema-map settings to prevent data exposure.

  • Verify encryption settings to prevent data exposure.
  • Review schema-map configurations to ensure protected fields are stored encrypted.

Technical summary

CVE-2026-92756 affects applications built on MongoDB Entity Framework Core Provider with combined independent and provider encryption settings, potentially leading to unencrypted storage of protected fields. This vulnerability arises from the interaction between independent encryption settings and the provider's encryption settings, which may cause silent loss of TLS and schema-map settings. As a result, sensitive data might be exposed due to unencrypted storage of protected fields. Developers and administrators should assess encryption configurations and verify schema-map settings to prevent data exposure.

Defensive priority

Assess MongoDB Entity Framework Core Provider encryption configurations and verify schema-map settings.

Recommended defensive actions

  • Review MongoDB Entity Framework Core Provider encryption settings and schema-map configurations.
  • Verify protected fields are stored encrypted in the database.
  • Update MongoDB Entity Framework Core Provider to ensure consistent encryption settings.
  • Assess the current encryption setup and verify schema-map configurations.
  • Implement compensating controls for exposed systems while remediation is scheduled and verified.
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented.
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.

Evidence notes

CVE description indicates potential data exposure due to encryption setting conflicts. The vulnerability arises when applications built on MongoDB Entity Framework Core Provider combine independent encryption settings with the provider's encryption settings. This conflict may cause protected fields to be stored unencrypted, leading to potential data exposure. Developers and administrators should verify encryption configurations and schema-map settings to prevent data exposure.
