MediaWiki Cross-site Scripting (XSS) vulnerability
In MediaWiki before 1.31.9 and 1.32.x through 1.34.x before 1.34.3, XSS related to jQuery can occur. The attacker creates a message with [javascript:payload xss] and turns it into a jQuery object with mw.message().parse(). The expected result is that the jQuery object does not contain an <a> tag (or it does not have a href attribute, or it's empty, etc.). The actual result is that the object contains an <a href ="javascript... that executes when clicked.
