Overview<\/strong><\/p>\n

This report examines CVE-2025-6713, a significant vulnerability in MongoDB Server that allows unauthorized data access. MongoDB Server users, particularly those using versions v8.0 prior to 8.0.7, v7.0 prior to 7.0.20, and v6.0 prior to 6.0.22, are affected by this vulnerability. It is crucial to address this issue as it can potentially lead to system compromise or data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-6713
\nSeverity: High (CVSS 7.7)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Unauthorized access to data, potential system compromise or data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

MongoDB Server | v8.0 prior to 8.0.7
\nMongoDB Server | v7.0 prior to 7.0.20
\nMongoDB Server | v6.0 prior to 6.0.22<\/p>\n

How the Exploit Works<\/strong><\/p>\n

An attacker can exploit this vulnerability by creating a specially crafted aggregation pipeline. The $mergeCursors stage in MongoDB Server improperly handles this pipeline, allowing the attacker to bypass authorization checks and gain unauthorized access to data.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a conceptual example of how the vulnerability might be exploited. The attacker sends a specially crafted HTTP request to the vulnerable MongoDB Server:<\/p>\n

POST \/vulnerable\/endpoint HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{\n\"aggregation_pipeline\":\n{\n\"$mergeCursors\":\n{\n\"source\": \"unauthorized_data_collection\",\n\"options\":\n{\n\"pipeline\": [\n{\"$match\": {\"_id\": \"target_record_id\"}},\n{\"$project\": {\"sensitive_field\": 1}}\n]\n}\n}\n}\n}<\/code><\/pre>\n
In this example, the attacker targets a specific record (“target_record_id”) in an unauthorized data collection (“unauthorized_data_collection”) and extracts a sensitive field (“sensitive_field”).<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
To mitigate this vulnerability, users are advised to apply the vendor patch. For MongoDB Server v8.0, upgrade to version 8.0.7 or later. For MongoDB Server v7.0, upgrade to version 7.0.20 or later. For MongoDB Server v6.0, upgrade to version 6.0.22 or later. As a temporary mitigation measure, users can also implement a Web Application Firewall (WAF) or Intrusion Detection System (IDS).<\/p>\n","protected":false},"excerpt":{"rendered":"
