SCA: security update for starcitizenwiki/embedvideo (GHSA-5c7p-g73q-rpg5)

high Tenable Self-Hosted Container Security Plugin ID 443722

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-55692)

Solution

Update the starcitizenwiki/embedvideo library and its related packages to version 4.1.0 or later.
