Database disclosure via unsanitized borrower identifier
Published Mar 31, 2026 · Updated Mar 31, 2026
Blind SQL injection in SourceCodester Loan Management System 1.0 allows remote authenticated users to infer database contents via HTTP. The ajax.php save_loan action uses the POST borrower_id value in an SQL query without adequate sanitization, enabling time-delay predicates. An authenticated application session is required, and the demonstrated consequence is byte-by-byte disclosure of database contents.
