SCA: security update for starcitizenwiki/embedvideo (GHSA-c29q-5xm7-5p62)

high Tenable Self-Hosted Container Security Plugin ID 443682

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,
 EmbedServiceFactory::newFromName in includes/EmbedService/EmbedServiceFactory.php interpolates an
 attacker-controlled unknown service name into exception text, and includes/EmbedVideo.php returns that
 text as HTML through the isHtml output path without neutralization. Both the #ev parser function and the
 evl parser form can reach this error path. A user able to edit a wiki page can inject stored HTML or
 JavaScript into the error output, causing code to execute in the wiki origin for visitors who render the
 page. This issue is fixed in version 4.1.0. (CVE-2026-55690)

Solution

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