Machine-written summary

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

XWiki Platform's xwiki-platform-icon-ui Maven package is vulnerable in versions from 6.2-milestone-1 up to 13.10.10, from 14.0 up to 14.4.6, and from 14.5 up to 14.9. A user who can create an icon theme, including users without edit rights through their own profile, can run wiki content with the rights of the IconThemeSheet author, which enables privilege escalation. Upgrade to 13.10.10, 14.4.6, or 14.9. The source's workaround is to apply a code change to the IconThemeSheet page, which is not practical for most readers, so upgrading is the recommended fix.
