Threats tagged 'ghsa-x3g7-fw87-vwjc'

SemanticMediaWiki versions from 2.5.0 up to but not including 7.3.1 contain a stored cross-site scripting (XSS) vulnerability. This flaw allows users with page-edit rights to inject malicious script via Code-typed property values. The vulnerability arises because attackers can embed HTML markup inside a valid JSON value, which is then rendered unescaped on the Special:Browse page, leading to JavaScript execution in the browsers of users viewing the page.
