The CreateRedirect extension before 2022-04-14 for MediaWiki does not properly check whether the user has permissions to edit the target page. This could lead to an unauthorised (or blocked) user being able to edit a page.
Add your gear to cvedb and we'll alert you only when mediawiki ships something exploited.
