Description Adam Mariš 2017-08-02 07:12:24 EDT

When a call-site passes a subject for an email that contains line-breaks, the caller can add arbitrary SMTP headers.

This vulnerability can be mitigated for older versions of Commons Email by stripping line-breaks from the subject before passing it to the setSubject(String) method.
