"The version of TYPO3 installed on the remote host is 9.5.12 prior to 9.5.17 or 10.2 prior to 10.4.2. It is, 
therefore, affected by a cross-site scripting (XSS) vulnerability in its link handling component due to improper 
validation of user-supplied input before returning it to users. An authenticated, remote attacker can exploit
this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser 
session.
 
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version");
