Technical details

A reflected cross-site scripting (XSS) vulnerability exists in Typesetter CMS versions <= 5.1 within the include/tool/Editing.php file. The vulnerability is caused by the 'images' parameter (submitted as images[] in a POST request) being reflected into an HTML href attribute without proper context-aware output encoding. An authenticated attacker with editing privileges can exploit this by supplying a JavaScript pseudo-protocol (e.g., javascript:). Successful exploitation requires user interaction and allows for arbitrary JavaScript execution in the victim's browser session. As of the advisory date, the project appears to be unmaintained, and no official patch has been confirmed.
