CVE-2026-49048 in JoomCCK Extension
Summary
by MITRE • 06/28/2026
The Joomla extension JoomCCK exposes a front-end controller task, that builds two SQL statements by directly concatenating a user-supplied request parameter into the query string without escaping or parameterisation.

This vulnerability exists within the Joomla extension JoomCCK where a front-end controller task processes user input through direct string concatenation rather than proper parameterization or escaping mechanisms. The flaw allows an attacker to inject malicious SQL content directly into database queries through request parameters, creating a classic sql injection vulnerability that falls under CWE-89. When user-supplied data is incorporated into SQL statements without proper sanitization, it creates an opening for attackers to manipulate database operations and potentially extract sensitive information or execute unauthorized commands.
The technical implementation of this vulnerability occurs when the extension's controller receives a parameter from the front-end and directly appends it to SQL query strings without any form of input validation or escaping. This approach violates fundamental security principles and creates a path for attackers to exploit the system by crafting malicious requests that contain sql payload fragments. The lack of parameterization means that any special characters within user input can alter the intended structure of the sql statement, potentially allowing full database compromise.
The operational impact of this vulnerability is significant as it provides remote attackers with the ability to perform unauthorized database operations without authentication. Attackers could extract sensitive data such as user credentials, personal information, or system configuration details from the database. The vulnerability also enables potential data manipulation and deletion operations that could compromise system integrity and availability. According to ATT&CK framework, this represents a technique categorized under T1071.004 for application layer protocol and T1566 for credential access through exploitation of vulnerabilities. The exposure occurs at the application level where the extension fails to implement proper input sanitization mechanisms.
Mitigation strategies should focus on implementing proper parameterized queries or prepared statements that separate sql logic from user data. All user-supplied parameters must be validated and sanitized before being incorporated into database operations, with input filtering applied at multiple layers of the application architecture. Additionally, implementing proper access controls and least privilege principles can limit the potential damage from successful exploitation attempts. Security measures should include regular code reviews to identify similar patterns, automated vulnerability scanning during development cycles, and adherence to secure coding standards that prevent such injection vulnerabilities from being introduced in the first place. The extension developers should also consider implementing web application firewall rules to detect and block suspicious sql injection attempts while maintaining proper logging and monitoring capabilities for security event detection.
