Description
XWiki Platform Mentions UI is a user interface for mentioning users in wiki content for XWiki Platform, a generic wiki platform. Starting in version 12.5-rc-1 and prior to versions 13.10.6 and 14.4, it's possible to store Javascript or groovy scripts in a mention, macro anchor, or reference field.

As a workaround, one may update XWiki.Mentions.MentionsMacro and edit the Macro code field of the XWiki.WikiMacroClass XObject.
