CVE-2026-3022: Wakyma NoSQL Injection Vulnerability

CVE-2026-3022 Overview

A NoSQL injection (NoSQLi) vulnerability has been identified in the Wakyma web application, specifically affecting the vets.wakyma.com/hospitalization/generate-hospitalization-summary endpoint. This vulnerability allows an authenticated user to manipulate POST requests to inject special NoSQL commands, potentially enabling unauthorized access to customer reports and sensitive data.

Critical Impact

Authenticated attackers can exploit this NoSQL injection to bypass authorization controls and exfiltrate sensitive customer hospitalization reports from the Wakyma veterinary management platform.

Affected Products

• Wakyma Web Application (all versions)
• Wakyma Hospitalization Module
• Wakyma Veterinary Management System

Technical Details for CVE-2026-3022

Vulnerability Analysis

This NoSQL injection vulnerability exists in the Wakyma web application's hospitalization summary generation endpoint. The flaw occurs when user-supplied input in POST requests is not properly sanitized before being incorporated into NoSQL database queries. An authenticated attacker can craft malicious requests containing NoSQL operators and commands that alter the intended query logic.

The vulnerability is classified under CWE-943 (Improper Neutralization of Special Elements in Data Query Logic) and CWE-89 (SQL Injection), indicating that the application fails to neutralize special characters and operators that have significance in NoSQL query languages such as MongoDB query syntax.

The attack requires network access and low-privilege authenticated access to the application. No user interaction is required for exploitation. The primary impact is a complete breach of confidentiality, allowing attackers to access sensitive customer hospitalization reports they would not normally be authorized to view.

Root Cause

The root cause of this vulnerability is insufficient input validation and sanitization in the generate-hospitalization-summary endpoint. The application directly incorporates user-controlled parameters into NoSQL queries without proper escaping or parameterization. This allows attackers to inject NoSQL-specific operators such as $gt, $ne, $regex, $where, and similar commands that can modify query behavior.

Attack Vector

The attack is performed over the network against the vets.wakyma.com/hospitalization/generate-hospitalization-summary endpoint. An authenticated user can modify POST request parameters to include NoSQL injection payloads. These payloads typically leverage MongoDB query operators to bypass authentication checks, extract data from other records, or enumerate sensitive information.

A typical attack scenario involves an authenticated low-privilege user intercepting their legitimate POST request to the hospitalization summary endpoint and modifying parameters to include NoSQL operators. For example, injecting operators like {"$ne": null} or {"$gt": ""} in place of expected values can cause the query to return records beyond the attacker's authorization scope.

The vulnerability can be exploited to access customer reports, potentially exposing sensitive veterinary patient information, owner contact details, and hospitalization records belonging to other users of the platform.

Detection Methods for CVE-2026-3022

Indicators of Compromise

• Unusual POST request patterns to the /hospitalization/generate-hospitalization-summary endpoint containing MongoDB operators such as $gt, $ne, $or, $regex, or $where
• Requests containing JSON structures with unexpected nested objects or dollar-sign prefixed keys in parameter values
• Anomalous data access patterns where users retrieve hospitalization reports outside their normal scope
• HTTP request bodies containing encoded or obfuscated NoSQL query operators

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common NoSQL injection patterns including MongoDB query operators in POST request parameters
• Deploy application-level logging to capture all requests to the vulnerable endpoint with full request body inspection
• Configure SIEM correlation rules to identify users accessing an abnormal volume or variety of customer reports
• Utilize SentinelOne Singularity platform for behavioral analysis and real-time threat detection of injection attack patterns

Monitoring Recommendations

• Enable detailed audit logging for all data access operations in the Wakyma hospitalization module
• Monitor for authentication anomalies followed by bulk data access attempts
• Set up alerts for requests containing suspicious characters or patterns commonly associated with NoSQL injection attacks
• Review access logs for the affected endpoint to identify potential exploitation attempts

How to Mitigate CVE-2026-3022

Immediate Actions Required

• Restrict access to the generate-hospitalization-summary endpoint to only essential personnel until a patch is available
• Implement additional authentication controls and rate limiting on the affected endpoint
• Deploy WAF rules to block requests containing known NoSQL injection patterns
• Review and audit recent access logs for signs of exploitation
• Consider temporarily disabling the hospitalization summary generation feature if feasible

Patch Information

No official patch information has been published at this time. Organizations should monitor the INCIBE Security Notice for updates regarding vendor patches and remediation guidance. Contact the Wakyma vendor directly for patch availability and deployment instructions.

Workarounds

• Implement strict input validation on all user-supplied parameters, rejecting any input containing NoSQL operators or special characters
• Use parameterized queries or prepared statements appropriate for your NoSQL database to prevent injection attacks
• Apply the principle of least privilege to database accounts used by the application, limiting query capabilities
• Deploy a reverse proxy or WAF with NoSQL injection detection capabilities in front of the Wakyma application
• Segment network access to the Wakyma application to reduce exposure to potential attackers
