Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The xwiki-platform-rendering-wikimacro-store Maven package is vulnerable in versions 11.4 up to 11.10.11, 12.0 up to 12.6.3, and 12.7 up to 12.8. The {{wikimacrocontent}} macro runs its content with the rights of the wiki macro's author rather than the caller, so an attacker who can inject script into a wiki macro that uses it can run code with that author's rights, often a user with Programming rights. Upgrade to 11.10.11, 12.6.3, or 12.8. The source gives no workaround beyond disabling the affected macros.
