* Fix second-order SQL injection in currency_symbol config The currency_symbol value was concatenated directly into SQL queries without proper escaping, allowing SQL injection attacks via the Summary Discounts report. Changes: - Use $this->db->escape() in Summary_discounts::getData() to properly escape the currency symbol value before concatenation - Add htmlspecialchars() validation in Config::postSaveLocale() to sanitize the input at storage time - Add unit tests to verify escaping of malicious inputs Fixes SQL injection vulnerability described in bug report where attackers with config permissions could inject arbitrary SQL through the currency_symbol field. * Update test to use CIUnitTestCase for consistency Per code review feedback, updated test to extend CIUnitTestCase instead of PHPUnit TestCase to maintain consistency with other tests in the codebase. --------- Co-authored-by: Ollama <ollama@steganos.dev>
