Machine-written summary

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

XWiki Platform web templates (xwiki-platform-web-templates) from 12.0-rc-1 before 14.10.12, and from 15.0-rc-1 before 15.5-rc-1, have a reflected XSS flaw in the create document form when name validation is enabled, which is off by default. An attacker who gets a user to open a crafted link can act with that user's rights. Upgrade to 14.10.12 or 15.5-rc-1.
