SCA: security update for org.xwiki.rendering:xwiki-rendering-xml (GHSA-663w-2xp3-5739)

critical Tenable Self-Hosted Container Security Plugin ID 411231

Description

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

 - XWiki Rendering is a generic Rendering system that converts textual input in a given syntax into another
 syntax. The cleaning of attributes during XHTML rendering, introduced in version 14.6-rc-1, allowed the
 injection of arbitrary HTML code and thus cross-site scripting via invalid attribute names. This can be
 exploited, e.g., via the link syntax in any content that supports XWiki syntax like comments in XWiki.
 When a user moves the mouse over a malicious link, the malicious JavaScript code is executed in the
 context of the user session. When this user is a privileged user who has programming rights, this allows
 server-side code execution with programming rights, impacting the confidentiality, integrity and
 availability of the XWiki instance. While this attribute was correctly recognized as not allowed, the
 attribute was still printed with a prefix `data-xwiki-translated-attribute-` without further cleaning or
 validation. This problem has been patched in XWiki 14.10.4 and 15.0 RC1 by removing characters not allowed
 in data attributes and then validating the cleaned attribute again. There are no known workarounds apart
 from upgrading to a version including the fix. (CVE-2023-37908)
