Description (CNA)
The EmbedVideo Extension is a MediaWiki extension which adds a parser function called #ev and various parser tags for embedding video clips from various video sharing services. Prior to 4.1.0, with the default $wgEmbedVideoRequireConsent configuration enabled, includes/EmbedService/EmbedHtmlFormatter.php places JSON returned through includes/EmbedService/AbstractEmbedService.php into the data-mw-iframeconfig attribute without safely escaping single quotes. Attacker-controlled archiveorg identifiers and wistia or sharepoint URLs accepted by the affected service validators can cause getUrl() output to terminate the attribute and inject event-handler attributes into the generated figure element. A user able to edit a wiki page can store JavaScript that executes in the wiki origin when visitors render the page. This issue is fixed in version 4.1.0.
