🎯 What: Fixed SQL Injection vulnerability in MainController.loadBookInfo2.
⚠️ Risk: Attackers could inject arbitrary SQL commands via the bookID input field, potentially compromising database integrity and confidentiality.
🛡️ Solution: Refactored the vulnerable query into a new method DataHelper.getIssueDetails that uses PreparedStatement with parameterized queries. The method now also throws SQLException to allow proper error handling by the caller.
