Joomla JoomCCK SQL Injection Vulnerability

CVE advisorySeverity: HIGH (CVSS 8.7)

CVE-2026-49048

JoomCCK is a Joomla extension used to manage content and data on web sites. As a front-end component designed to process user-supplied parameters, it is intended to be accessible to visitors of the public-facing website, making it a likely component of an internet-reachable web application surface.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory concerns a vulnerability in the JoomCCK extension for Joomla, which could allow unauthorized access and manipulation of data. The issue arises from how the extension handles user input, potentially leading to severe security risks if exploited. The primary concern is to confirm whether this specific extension is in use within our environment and, if so, to assess the potential exposure.

  • User input allows direct database manipulation.
  • Critical vulnerability in a Joomla content extension.
  • Confirm relevance and exposure for affected systems.

Attack Path

How an attacker could exploit the issue

Attackers can exploit this vulnerability by sending a specially crafted request to a Joomla website that uses the JoomCCK extension. This request targets a front-end controller that fails to properly sanitize a user-supplied parameter. By manipulating this parameter, an attacker can inject malicious SQL code, which the application then executes. This could allow an attacker to steal sensitive data, modify database contents, or even take control of the affected website.

  • No authentication or special access needed.
  • Vulnerable controller concatenates user input.
  • Database compromise, data theft, or site control.

Live Threat

Current exploitation, exposure, and threat context

When supported by the advisory, this vulnerability could allow an unauthenticated attacker to inject malicious SQL code into the JoomCCK extension. This could lead to unauthorized access to or modification of sensitive data stored within the Joomla installation.

  • Joomla content and database data.
  • Malicious SQL injection.
  • Data compromise or modification.

Operational Fix

Recommended remediation, mitigation, and detection steps

The Joomla extension JoomCCK's critical SQL injection vulnerability, which allows unauthenticated remote attackers to execute arbitrary SQL commands, requires immediate attention from teams managing web application infrastructure and content. The first actionable step is to identify all instances of JoomCCK within your environment, confirm their public accessibility and business criticality, and then assign ownership for remediation planning.

  • Identify Joomla site owners and administrators.
  • Verify JoomCCK accessibility and criticality.
  • Plan remediation based on risk exposure.

Frequently asked questions

What is the JoomCCK extension for Joomla?

JoomCCK is a content construction kit and data management extension for Joomla. It allows site administrators to create custom content types and organize complex data structures directly within their website. Because it provides front-end interfaces to interact with this data, it is commonly used to power dynamic web pages, directories, and user-submitted content portals that visitors interact with regularly.

Why is CVE-2026-49048 considered a SQL injection vulnerability?

This vulnerability falls under the weakness class CWE-89, which refers to improper neutralization of special elements used in an SQL command. In the context of CVE-2026-49048, the software fails to sanitize input, allowing malicious SQL code to be appended to a query. This enables the database to execute unintended commands, potentially granting an attacker access to view, modify, or delete sensitive information contained in the site's database.

How does an attacker trigger this vulnerability?

An attacker triggers this flaw by sending a specially crafted request to the JoomCCK front-end controller. The application takes a parameter from this request and directly inserts it into an SQL query. Notably, this does not require any prior authentication or special user privileges; the system accepts and processes the malicious input automatically as part of the normal request handling cycle, provided the vulnerable controller is reachable.

Is my website at risk from this CVE?

Halo Surface Signal notes that because JoomCCK is designed as a front-end component for public interaction, it is frequently exposed on the internet-reachable surface of a web application. If your Joomla site uses JoomCCK and is accessible to the public, you should assume it is potentially vulnerable to these crafted requests. Systems that are not connected to the internet or do not use this specific extension are not directly impacted.

How should I respond to this threat advisory?

The most effective first step is to inventory your Joomla installations to determine if the JoomCCK extension is present and active. Once identified, evaluate the business criticality of those specific sites. Prioritize your response by confirming which instances are internet-facing, as these represent the most immediate path for an attacker. Assign responsibility to the appropriate site administrators to oversee remediation once updates or patches become available.
