CVE-2026-3023: Wakyma NoSQL Injection Vulnerability

CVE-2026-3023 Overview

CVE-2026-3023 is a Non-relational SQL injection vulnerability (NoSQLi) affecting the Wakyma web application. The vulnerability exists specifically in the endpoint vets.wakyma.com/pets/print-tags. This security flaw allows an authenticated user to alter a POST request to the affected endpoint for the purpose of injecting NoSQL commands, enabling unauthorized access to list both pets and owner names from the database.

Critical Impact

Authenticated attackers can exploit this NoSQL injection vulnerability to extract sensitive pet and owner information from the Wakyma database through crafted POST requests to the print-tags endpoint.

Affected Products

• Wakyma Web Application (all versions)
• Wakyma vets.wakyma.com domain services
• Wakyma /pets/print-tags endpoint functionality

Technical Details for CVE-2026-3023

Vulnerability Analysis

This NoSQL injection vulnerability (CWE-943, CWE-89) occurs due to improper input validation in the Wakyma web application's pet tag printing functionality. The vulnerable endpoint accepts POST requests that are not properly sanitized before being passed to the underlying NoSQL database query engine.

The attack requires authentication, meaning an attacker must first obtain valid credentials or an active session to exploit this vulnerability. Once authenticated, the attacker can manipulate POST parameters sent to the /pets/print-tags endpoint to inject malicious NoSQL operators and commands. This exploitation technique allows the attacker to bypass intended query restrictions and retrieve data beyond their authorization level.

The vulnerability is network-accessible with low attack complexity, requiring no user interaction beyond the initial authentication. The primary impact is on data confidentiality, as attackers can enumerate and extract pet records and associated owner names that they should not have access to.

Root Cause

The root cause of CVE-2026-3023 stems from insufficient input sanitization and lack of parameterized queries in the Wakyma application's backend. The /pets/print-tags endpoint directly incorporates user-supplied POST data into NoSQL database queries without proper escaping or validation. This allows attackers to inject NoSQL-specific operators such as $ne, $gt, $regex, or $where clauses that alter the intended query logic.

NoSQL databases like MongoDB use JSON-like query structures, and when user input is concatenated directly into these queries, injection attacks become possible. The application fails to implement proper input validation patterns or use secure query building practices that would prevent malicious operators from being interpreted as database commands.

Attack Vector

The attack vector for this vulnerability is network-based, targeting the authenticated POST endpoint at vets.wakyma.com/pets/print-tags. An authenticated attacker crafts a malicious POST request containing NoSQL injection payloads in the request parameters.

Typical NoSQL injection techniques that may be applicable include injecting comparison operators to bypass filters, using regex operators to enumerate data, or leveraging JavaScript execution operators in databases that support them. The attacker manipulates the query structure to return all pet records and their associated owner information, regardless of intended access restrictions.

For example, an attacker might inject operators that modify the query's filter conditions to always evaluate as true, effectively dumping the entire collection. The exploitation requires understanding of the underlying NoSQL database structure and the parameter names expected by the endpoint.

Detection Methods for CVE-2026-3023

Indicators of Compromise

• Unusual POST requests to /pets/print-tags containing NoSQL operators such as $ne, $gt, $lt, $regex, $where, or $exists
• Abnormal response sizes from the print-tags endpoint indicating bulk data extraction
• Multiple rapid requests to the vulnerable endpoint from a single authenticated session
• Database query logs showing unexpected operators or modified query structures

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect NoSQL injection patterns in POST request bodies
• Monitor application logs for requests containing common NoSQL injection operators and JSON syntax anomalies
• Deploy runtime application self-protection (RASP) solutions to detect query manipulation attempts
• Analyze authentication logs for accounts making unusual patterns of requests to the affected endpoint

Monitoring Recommendations

• Enable detailed logging for all requests to the /pets/print-tags endpoint including full POST body content
• Set up alerts for requests containing suspicious characters or NoSQL-specific syntax patterns
• Monitor database query performance metrics for anomalies that may indicate injection-based data enumeration
• Review access patterns for the vulnerable endpoint to identify potential exploitation attempts

How to Mitigate CVE-2026-3023

Immediate Actions Required

• Restrict access to the /pets/print-tags endpoint to only trusted users or disable the functionality until patched
• Implement additional authentication controls such as IP whitelisting for the affected endpoint
• Deploy WAF rules to block requests containing known NoSQL injection patterns
• Review and audit all accounts that have accessed the vulnerable endpoint for signs of exploitation

Patch Information

No official patch information is currently available from the vendor. Organizations should monitor the INCIBE Security Notice for updates on available fixes. Contact Wakyma directly for guidance on remediation and expected patch timeline.

Workarounds

• Implement server-side input validation to sanitize all POST parameters before database query construction
• Use parameterized queries or ORM frameworks that automatically escape user input to prevent injection
• Apply the principle of least privilege to database accounts used by the application to limit exposure from successful exploitation
• Consider implementing rate limiting on the affected endpoint to slow potential data extraction attempts

# Add to your WAF configuration to detect injection attempts

# Block requests containing NoSQL operators in POST body
