CVE-2017-5223: Local File Disclosure

January 16, 2017 (updated October 28, 2017)

PHPMailer’s msgHTML method applies transformations to an HTML document to make it usable as an email message body. One of the transformations is to convert relative image URLs into attachments using a script-provided base directory. If no base directory is provided, it resolves to /, meaning that relative image URLs get treated as absolute local file paths and added as attachments.
