CVE-2026-3021 in Application Web
Summary
by MITRE • 03/16/2026
Non-relational SQL injection vulnerability (NoSQLi) in the Wakyma web application, specifically in the endpoint 'vets.wakyma.com/centro/equipo/empleado'. This vulnerability could allow an authenticated user to alter a GET request to the affected endpoint for the purpose of injecting special NoSQL commands. This would lead to the enumeration of sensitive employee data.

The vulnerability identified as CVE-2026-3021 represents a critical non-relational sql injection flaw within the Wakyma web application ecosystem. This security weakness specifically targets the endpoint located at vets.wakyma.com/centro/equipo/empleado which serves employee-related functionality within the application's administrative interface. The flaw stems from insufficient input validation and sanitization mechanisms that fail to properly handle malicious NoSQL command sequences submitted through GET request parameters. The vulnerability classifies under CWE-94 as it involves the execution of untrusted code through improper input handling, while also aligning with ATT&CK technique T1213.002 for data from information repositories where unauthorized access to employee records could be achieved through command injection.
The technical implementation of this vulnerability allows an authenticated user to manipulate the GET request parameters sent to the targeted endpoint. When the application processes these requests without adequate filtering or escaping of special NoSQL operators such as $or, $and, $ne, or $regex, malicious payloads can be interpreted as legitimate database commands rather than user input. This misinterpretation enables attackers to construct queries that bypass normal access controls and extract sensitive employee information including personal details, employment records, and potentially system access credentials. The NoSQL injection occurs at the application layer where user-supplied data flows directly into database query construction without proper sanitization, creating a direct pathway for unauthorized data enumeration.
The operational impact of this vulnerability extends beyond simple data exposure, as it fundamentally undermines the security controls designed to protect employee information within the Wakyma application. An attacker with valid credentials could systematically enumerate employee records, potentially identifying high-value targets for further social engineering attacks or credential compromise attempts. The authenticated nature of the vulnerability means that attackers do not require privileged accounts to exploit this weakness, making it particularly dangerous within environments where employee access is widespread. This vulnerability could facilitate insider threat scenarios where legitimate users leverage their access to extract sensitive information beyond their authorized scope, while also enabling external attackers who gain initial access through other means to escalate their privileges and extract comprehensive employee datasets.
Mitigation strategies for CVE-2026-3021 should prioritize immediate implementation of parameter validation and sanitization controls within the affected endpoint. The application layer must employ strict input filtering that removes or encodes special NoSQL operators before processing user-supplied data. Additionally, implementing proper query parameterization techniques and using secure coding practices that prevent direct injection of user input into database queries will significantly reduce the attack surface. Organizations should also consider implementing web application firewalls with rules specifically designed to detect and block NoSQL injection patterns, along with regular security testing including automated vulnerability scanning and manual penetration testing. The implementation of principle of least privilege access controls and mandatory access controls for employee data would provide additional defense in depth measures, while regular security awareness training for administrators can help prevent exploitation through social engineering or credential compromise attacks.
