CVE-2017-6100 describes a vulnerability in tcpdf prior to version 6.2.0, where the PDF generation process could inadvertently upload files from the server to an external FTP server. This high-severity vulnerability (CVSS 7.5) is easily exploitable over the network without user interaction, potentially leading to unauthorized disclosure of sensitive information.
