SCA: security update for phpmailer/phpmailer (GHSA-4x5h-cr29-fhp6)

medium Tenable Self-Hosted Container Security Plugin ID 422186

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - An issue was discovered in PHPMailer before 5.2.22. 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. To form a remote vulnerability, the msgHTML method must be called, passed an
 unfiltered, user-supplied HTML document, and must not set a base directory. (CVE-2017-5223)
