The logIn() and signUp() functions build queries by directly concatenating user input and unvalidated table names, without using prepared statements. This allows an attacker to manipulate the SQL query, thereby causing <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-50341-sql-injection-vulnerability-in-axelor-5-2-4\/\"  data-wpil-monitor-id=\"74521\">SQL Injection<\/a>. While a prepareData() function exists, it is insufficient to prevent SQL injection as it does not sanitize the table name, leaving the <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-27046-critical-memory-corruption-vulnerability-threatening-system-integrity\/\"  data-wpil-monitor-id=\"75053\">system vulnerable<\/a> to attacks.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-4206030477\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>An attacker could exploit this vulnerability by sending a malicious <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-47982-improper-input-validation-vulnerability-in-windows-storage-vsp-driver-leading-to-privilege-escalation\/\"  data-wpil-monitor-id=\"75559\">SQL<\/a> statement in the user input.
