Description

Any user with view rights on commonly accessible documents including the icon picker macro can execute arbitrary Groovy, Python or Velocity code in XWiki due to improper neutralization of the macro parameters of the icon picker macro. The problem has been patched in XWiki 13.10.7, 14.5 and 14.4.2. Workarounds: The [patch](https://github.com/xwiki/xwiki-platform/commit/47eb8a5fba550f477944eb6da8ca91b87eaf1d01) can be manually applied by editing `IconThemesCode.IconPickerMacro` in the object editor.
