Overview

CVE-2025-14345 is a medium-severity vulnerability. It was published on December 9, 2025 and has a CVSS 3.1 base score of 4.2 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.2, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

A post-authentication flaw in the network two-phase commit protocol used for cross-shard transactions in MongoDB Server may lead to logical data inconsistencies under specific conditions which are not predictable and exist for a very short period of time. This error can cause the transaction coordination logic to misinterpret the transaction as committed, resulting in inconsistent state on those shards. This may lead to low integrity and availability impact.

This issue impacts MongoDB Server v8.0 versions prior to 8.0.16, MongoDB Server v7.0 versions prior to 7.0.26 and MongoDB server v8.2 versions prior to 8.2.2.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
