CVE-2024-56408

Date: January 3, 2025

PhpSpreadsheet is a PHP library for reading and writing spreadsheet files. Versions prior to 3.7.0, 2.3.5, 2.1.6, and 1.29.7 have no sanitization in the "/vendor/phpoffice/phpspreadsheet/samples/Engineering/Convert-Online.php" file, which leads to the possibility of a cross-site scripting attack. Versions 3.7.0, 2.3.5, 2.1.6, and 1.29.7 contain a patch for the issue.
