or steal data from the user.\nIn order to activate this, the following sequence must occur:\n\n\n\n  *  Log4cxx is configured to use HTMLLayout.\n\n  *  Logger name comes from an untrusted string\n\n  *  Logger with compromised name logs a message\n\n  *  User opens the generated HTML log file in their browser, leading to potential XSS\n\n\nBecause logger names are generally constant strings, we
