Name of the Vulnerable Software and Affected Versions Maxthon3 versions prior to 3.3

Description Maxthon3 versions prior to 3.3 are vulnerable to cross context scripting (XCS) through the about:history page. The browser’s trusted zone improperly handles injected script content, allowing attackers to execute arbitrary JavaScript in a privileged context. This flaw enables modification of browser configuration and execution of arbitrary code through Maxthon’s exposed DOM APIs, including maxthon.program.Program.launch() and maxthon.io.writeDataURL(). Exploitation requires user interaction, typically by visiting a malicious webpage that triggers the injection.

Recommendations Update Maxthon3 to version 3.3 or later.
