CVE-2025-66474

8.7 highEPSS 1.0%

High (8.7) in xwiki xwiki-rendering. EPSS 1.0% chance of exploitation in the next 30 days. Fixed in org.xwiki.rendering:xwiki-rendering-xml 16.10.10, 17.4.3, 17.6.0-rc-1.

XWiki Rendering is a generic rendering system that converts textual input in a given syntax (wiki syntax, HTML, etc) into another syntax (XHTML, etc). Versions 16.10.9 and below, 17.0.0-rc-1 through 17.4.2 and 17.5.0-rc-1 through 17.5.0 have insufficient protection against {{/html}} injection, which attackers can exploit through RCE. Any user who can edit their own profile or any other document can execute arbitrary script macros, including Groovy and Python macros, which enable remote code execution as well as unrestricted read and write access to all wiki contents. This issue is fixed in versions 16.10.10, 17.4.3 and 17.6.0-rc-1.
