It has been reported that Liferay Enterprise Portal is susceptible to multiple cross-site scripting and HTML injection vulnerabilities. User-supplied data from many input fields is included in server generated content without appropriate validation/encoding. This may allow for typical cross-site scripting attacks against other users of the portal.
Test:
Add a message with subject <script>history.go(-1)</script>
