SCA: security update for org.xwiki.platform:xwiki-platform-rendering-macro-rss (GHSA-c885-89fw-55qr)

critical Tenable Self-Hosted Container Security Plugin ID 413769

Description

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

 - XWiki Commons are technical libraries common to several other top level XWiki projects. The RSS macro that
 is bundled in XWiki included the content of the feed items without any cleaning in the HTML output when
 the parameter `content` was set to `true`. This allowed arbitrary HTML and in particular also JavaScript
 injection and thus cross-site scripting (XSS) by specifying an RSS feed with malicious content. With the
 interaction of a user with programming rights, this could be used to execute arbitrary actions in the
 wiki, including privilege escalation, remote code execution, information disclosure, modifying or deleting
 content and sabotaging the wiki. The issue has been patched in XWiki 14.6 RC1, the content of the feed is
 now properly cleaned before being displayed. As a workaround, if the RSS macro isn't used in the wiki, the
 macro can be uninstalled by deleting `WEB-INF/lib/xwiki-platform-rendering-macro-rss-XX.jar`, where `XX`
 is XWiki's version, in the web application's directory. (CVE-2023-29202)
