Due to insufficient escaping of single quotes in the class SQLString, an attacker can exploit this issue via blind <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-50972-sql-injection-vulnerability-in-abantecart-1-4-2-with-a-high-severity-score\/\"  data-wpil-monitor-id=\"83481\">SQL injection<\/a>. This means that the attacker can insert malicious SQL commands into the application query, which can <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-22405-arbitrary-code-execution-vulnerability-leading-to-privilege-escalation\/\"  data-wpil-monitor-id=\"85473\">lead to the extraction of arbitrary<\/a> data from the database, if the database connection is configured to use the ODBC plugin.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p>\n<p>Below is a conceptual example of how the vulnerability might be exploited.
