XWiki Platform is a generic wiki platform. In multilingual wikis, translations can be edited by any user who has edit right, circumventing the rights that are normally required for authoring translations (script right for user-scope translations, wiki admin for translations on the wiki). Starting in version 4.3-milestone-2 and prior to versions 4.10.20, 15.5.4, and 15.10-rc-1, this can be exploited for remote code execution if the translation value is not properly escaped where it is used. This has been patched in XWiki 14.10.20, 15.5.4 and 15.10RC1. As a workaround, one may restrict edit rights on documents that contain translations.
