An issue was discovered in the ArticleRatings extension for MediaWiki through 1.42.1. Special:ChangeRating allows CSRF to alter data via a GET request.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
