5.6 MEDIUM

Confidentiality-only exposure of data that should be encrypted (C:H, I/A:N); the specific connection-string precondition maps to AC:H, exposure of the datastore is a scope change (S:C), and access-gated so PR:L.

DescriptionCVE.org

Applications built on MongoDB Entity Framework Core Provider which place a database name in the connection string may inadvertently disable field level encryption.

AnalysisAI

Field level encryption can be silently disabled in applications built on the MongoDB Entity Framework Core Provider when the connection string places a database name there, causing sensitive fields to be stored or read without the intended protection. This affects only applications that rely on field level encryption to protect sensitive data; deployments not using FLE are unaffected. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the specific, developer-introduced configuration where an application built on the MongoDB Entity Framework Core Provider places a database name directly in the connection string; this inadvertently disables field level encryption. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a data-protection weakness (CWE-311, Missing Encryption of Sensitive Data), not a memory-corruption or code-execution flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation No vendor-released patch version is identified in the available data; consult MongoDB Jira EF-389 (https://jira.mongodb.org/browse/EF-389) for patch status and version-specific guidance. … Detailed patch versions, workarounds, and compensating controls in full report.
