Applications built on MongoDB Entity Framework Core Provider which place a database name in the connection string may inadvertently disable field level encryption.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-92757) concerns the MongoDB Entity Framework Core Provider. When applications include a database name in the connection string, field level encryption may be inadvertently disabled, exposing sensitive data. The CVSS 4.0 base score is 6.8, indicating a medium severity with local attack vector, low attack complexity, and partial privileges required. The vulnerability affects versions >=8.3.1 <8.4.4, >=9.0.1 <9.1.4, and >=10.0.0 <10.0.4. No vendor advisory or patch links are provided in the input, so patch status is not confirmed.
Potential Impact
Sensitive data that should be encrypted at the field level may be exposed due to encryption being disabled when a database name is included in the connection string. This could lead to unauthorized access or disclosure of sensitive information within affected applications. The impact is limited by the need for local access and partial privileges as per the CVSS vector.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is confirmed, avoid placing the database name in the connection string or review application configurations to ensure field level encryption remains enabled. Monitor official MongoDB communications for updates and patches addressing this issue.
