CVE-2026-49048 -- CVSS 9.8 Vulnerability Briefing

CVE-2026-49048 | CVSS 9.8 (Critical) | Exploit: No known exploit

What Is It

CVE-2026-49048 is a critical SQL injection vulnerability in JoomCCK, a front-end content construction extension for Joomla developed by Joomcoder, exploitable through an unauthenticated HTTP request to a publicly accessible controller task.

Technical Detail

The vulnerability exists in a front-end controller task within JoomCCK that constructs two SQL queries by directly concatenating a user-supplied request parameter into the query string without sanitization or parameterization. An unauthenticated remote attacker can submit a crafted HTTP request containing malicious SQL syntax to manipulate query logic, enabling data extraction, authentication bypass, or potentially arbitrary write operations depending on database permissions and configuration. The CVSS score of 9.8 reflects the combination of network accessibility, no authentication requirement, and high impact across confidentiality, integrity, and availability.

Exploitation Status

No known exploit code has been publicly observed or confirmed as of July 5, 2026. This vulnerability is not currently listed in the CISA Known Exploited Vulnerabilities catalog. While no active exploitation has been documented, the unauthenticated nature and critical severity of this flaw make it a high-priority target for opportunistic scanning and exploitation once technical details become more widely circulated.

Who Is Targeting This

No specific threat actor attribution at this time. No confirmed threat actors have been linked to exploitation of this vulnerability. Reported attribution carries only medium confidence with no identified origin or motivation, and no public attribution has been established.

What To Do

Apply any available patch or updated version of JoomCCK from Joomcoder immediately, prioritizing internet-facing Joomla installations. If no patch is available, disable or remove the JoomCCK extension until a fix is released. As an interim measure, implement a web application firewall rule to block requests containing SQL metacharacters targeting the affected controller task endpoint. Review web server and database access logs for anomalous query patterns or unexpected parameter values submitted to JoomCCK controller routes. Restrict database account privileges used by the Joomla application to the minimum necessary to limit the impact of successful exploitation. Monitor Joomcoder's official channels and the Joomla Extensions Directory for security advisories and updated releases.
