In case anyone needs this:

A script for finding vulnerable versions of PHPMailer on a server:

https://gist.github.com/cebe/d0f5631b432c520a2e6f6be8beddf11...

Finds also really old versions like 2.0.4.

Find is a powerful tool:

    find /var/www -name 'class.phpmailer.php' -print -exec grep -ni '%s["'\''], $this->Sender' {} \;

still facebook will know where you have been. "Anonymous" and "Facebook" do not really fit together ;)

They already do. They have Like buttons everywhere on the web.

But Facebook does have a good security track record. This random website does not. I don't trust them with any more information than needed. In this case, that is only a single anonymized token.

PSR-4 does not require any case for namespaces:

> Alphabetic characters in the fully qualified class name MAY be any combination of lower case and upper case. http://www.php-fig.org/psr/psr-4/
