Mojo Mail does not filter HTML tags from URI parameters, making it prone to cross-site scripting attacks.
As a result, it is possible for a remote attacker to create a malicious link containing script code which will be executed in the browser of a legitimate user, in the context of the website running Mojo Mail.
This issue may be exploited to steal cookie-based authentication credentials from legitimate users of the website running the vulnerable software.
