What it is

Mahara 16.10 before 16.10.7 and 17.04 before 17.04.5 and 17.10 before 17.10.2 have a Cross Site Scripting (XSS) vulnerability when a user enters invalid UTF-8 characters. These are now going to be discarded in Mahara along with NULL characters and invalid Unicode characters. Mahara will also avoid direct $_GET and $_POST usage where possible, and instead use param_exists() and the correct param_*() function to fetch the expected value.
