CVE-2024-8141Public exploitNetwork attack vector

Browser script execution via reflected database errors

Published Aug 25, 2024 · Updated Aug 26, 2024

Cross-site scripting in SourceCodester Daily Calories Monitoring Tool 1.0 allows remote authenticated users to run script in a browser. The add-calorie.php exception handler directly echoes PDOException::getMessage(), allowing crafted calorie_date or calorie_name values included in a database error to enter the HTML response without output encoding. Access to the calorie-entry function is required, and successful exploitation modifies rendered page content within the affected browser session.
