### Impact One can execute any wiki content with the right of IconThemeSheet author by creating an icon theme with the following content: ``` }}} {{async async="true"}} {{groovy}} println("Hello from Groovy!") {{/groovy}} {{/async}} {{{ ``` Can be done by creating a new page or even through the user profile for users not having edit right. ### Patches This has been patched in XWiki 14.9, 14.4.6, and 13.10.10. ### Workarounds An easy workaround is to actually fix the bug in the page `IconThemesCode.IconThemeSheet` by applying the following modification: https://github.com/xwiki/xwiki-platform/commit/48caf7491595238af2b531026a614221d5d61f38#diff-2ec9d716673ee049937219cdb0a92e520f81da14ea84d144504b97ab2bdae243R45 ### References https://jira.xwiki.org/browse/XWIKI-19731 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira](http://jira.xwiki.org) * Email us at [Security ML](mailto:[email protected])
