"The version of TYPO3 installed on the remote host is 8.3 prior to 8.7.27 or 9.x prior to 9.5.8. It is, therefore,
affected by a cross-site scripting (XSS) vulnerability in its t3 URL handling component due to improper validation of 
user-supplied input before returning it to users. An unauthenticated, 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");
