Vulnerability Overview: CVE-2025-14847
The critical security flaw, CVE-2025-14847, has been discovered in both MongoDB Community and Enterprise versions. It stems from poor access control and insecure settings, posing a risk of unauthorized remote access from untrusted networks.
The vulnerability affects network-exposed MongoDB services on TCP port 27017. Often, no authentication is needed or the authentication is weak, raising the risk of being compromised.
CIRT advises that to manage the risk of CVE-2025-14847, organizations using MongoDB should strengthen security immediately. MongoDB should not be publicly accessible and should only bind to localhost or trusted internal IPs. Strong authentication and access controls should be applied by enabling authorization, removing unused accounts, and following the least privilege principle. Organizations should upgrade to the latest patched MongoDB version and ensure all vendor fixes are implemented. In addition, network protections must restrict database access to trusted servers and block public connectivity through firewalls and ACLs.
