MDaemon Webmail (formerly WorldClient) has CSRF.

MDaemon Email Server 19 through 20.0.1 skips SpamAssassin checks by default for e-mail messages larger than 2 MB (and limits checks to 10 MB even with special configuration), which is arguably inconsistent with currently popular message sizes. This might interfere with risk management for malicious e-mail, if a customer deploys a server with sufficient resources to scan large messages.

MDaemon Email Server 17.5.1 allows XSS via the filename of an attachment to an email message.

MDaemon Webmail 14.x through 18.x before 18.5.2 has XSS (issue 1 of 2).
