Improperly built order clauses lead to a SQL injection vulnerability in the articles webservice endpoint.
AnalysisAI
SQL injection in Joomla CMS articles webservice endpoint allows remote attackers to execute arbitrary SQL queries through improperly constructed ORDER BY clauses, affecting all versions of Joomla CMS. The vulnerability exists in the com_content component's webservice endpoint and permits unauthenticated query manipulation. No CVSS score or patch version information is available at time of analysis, limiting severity quantification.
Technical ContextAI
The vulnerability stems from CWE-89 (SQL Injection) in Joomla CMS's content component webservice handler, where user-supplied input is insufficiently sanitized before being incorporated into SQL ORDER BY clauses. The articles webservice endpoint fails to properly validate or escape sort parameters, allowing attackers to inject malicious SQL syntax. Joomla is a PHP-based content management system; the affected CPE (cpe:2.3:a:joomla!_project:joomla!_cms:*:*:*:*:*:*:*:*) indicates all versions across all branches are potentially impacted. The root cause is improper input validation in query construction rather than parameterized query use.
RemediationAI
Consult the official Joomla Security Centre advisory at https://developer.joomla.org/security-centre/1028-20260302-core-sql-injection-in-com-content-articles-webservice-endpoint.html for vendor-released patch information and exact upgrade version. At time of analysis, no specific patched version is provided in available data. Interim mitigation may include disabling or restricting access to the com_content webservice endpoint if not required for production operations, and implementing Web Application Firewall rules to block SQL injection patterns in webservice requests. Apply patches immediately upon release from Joomla.
