A high-severity vulnerability has been identified in multiple products, which could allow an attacker to bypass security controls and access sensitive data. An authenticated but low-privileged user can leverage a specially crafted query to read and potentially modify data they are not authorized to see, posing a significant risk to data confidentiality and integrity.

The vulnerability stems from an improper authorization check within the aggregation pipeline feature of the affected products. An authenticated attacker with low-level privileges can construct a specially crafted aggregation pipeline query. When the system processes this malicious pipeline, it fails to properly enforce access controls, allowing the attacker to read and potentially modify data in collections that would normally be restricted, effectively bypassing the intended security model.

This vulnerability is rated as High severity with a CVSS score of 7.7. Successful exploitation could lead to a significant data breach, exposing sensitive customer information, intellectual property, or internal corporate data. The ability for an attacker to not only read but also potentially modify data (High Confidentiality and Integrity impact) poses a severe risk. This could result in regulatory fines (e.g., under GDPR, CCPA), reputational damage, loss of customer trust, and operational disruption if critical data is altered.

Immediate Action: Organizations should prioritize applying the security patches provided by the vendor across all affected products as soon as possible. Refer to the vendor's security advisory for specific patch information and installation instructions.

Proactive Monitoring: Monitor application and database logs for unusual or overly complex aggregation pipeline queries, particularly those originating from low-privileged user accounts. Implement alerts for frequent access denial errors, which could indicate reconnaissance or exploitation attempts. Analyze user access patterns for anomalies, such as an account suddenly accessing data collections or fields outside its normal scope of operations.

Compensating Controls: If patching is not immediately feasible, consider restricting or disabling the use of complex aggregation features for non-essential or low-privileged users. Implement a Database Firewall or Web Application Firewall (WAF) with rules designed to inspect and block known malicious pipeline structures. Enforce the principle of least privilege by reviewing and ensuring user accounts only have the absolute minimum permissions required for their roles.

Public Exploit Available: false

Given the High severity rating (CVSS 7.7) and the potential for a significant data breach, we strongly recommend that organizations identify all affected products within their environment and apply the vendor-supplied patches on an expedited basis. While this vulnerability is not currently listed in the CISA KEV catalog, its high impact on data confidentiality and integrity makes it an attractive target for attackers. Proactive patching is the most effective defense and should be treated as a high priority.
