Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The XWiki Blog Application (Maven package org.xwiki.contrib.blog:application-blog-ui) before version 9.14 is vulnerable to privilege escalation and remote code execution. Any user with edit rights on any page, typically any logged-in user, can add a blog post object to a page and embed script macro code in its content to run code. Upgrade to version 9.14, which runs blog post content with the rights of the post's author. No workaround is listed.
