September 16, 2015 (updated October 9, 2018)

It has been discovered, that it is possible to forge a link to a backend module, which contains a JavaScript payload. This JavaScript is executed, if an authenticated editor with access to the module follows the link that, is tricked to click on a certain HTML target. Because TYPO3 include a secret token unknown to an attacker in every URL, an exploit would not be feasible for these versions.
