Joomla Extension - phoca.cz - Unauthenticated SQL injection via attribute filter in Phoca Cart 5.0.0-6.1.6 - The a[] (attribute) and s[] (specification) GET array parameters on Phoca Cart's public shop items page are concatenated raw into SQL WHERE clauses without parameterization or escaping. An unauthenticated attacker can inject arbitrary SQL through these parameters, enabling full database extraction via time-based blind techniques.
