Can you explain this vulnerability to me?
This vulnerability is a stored Cross-Site Scripting (XSS) issue in the ApprovedRevs extension for MediaWiki. It occurs because system messages are inserted into raw HTML without proper escaping, allowing attackers to inject malicious JavaScript code. Attackers exploit this by using the uselang=x-xss language override to cause crafted message keys to be rendered unescaped, leading to the execution of injected scripts.
How can this vulnerability impact me? :
This vulnerability can allow attackers to execute arbitrary JavaScript in the context of users viewing affected MediaWiki pages. This can lead to theft of user credentials, session hijacking, defacement, or other malicious actions performed on behalf of the user.
