SCA: security update for org.xwiki.contrib.markdown:syntax-markdown-commonmark12 (GHSA-8g2j-rhfh-hq3r)

critical Tenable Cloud Security Plugin ID 434274

Description

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

 - XWiki Contrib's Syntax Markdown allows importing Markdown content into wiki pages and creating wiki
 content in Markdown. In versions starting from 8.2 to before 8.9, the Markdown syntax is vulnerable to
 cross-site scripting (XSS) through HTML. In particular, using Markdown syntax, it's possible for any user
 to embed Javascript code that will then be executed on the browser of any other user visiting either the
 document or the comment that contains it. In the instance that this code is executed by a user with admins
 or programming rights, this issue compromises the confidentiality, integrity and availability of the whole
 XWiki installation. This issue has been patched in version 8.9. (CVE-2025-46558)
