### Impact It's possible for a user to execute anything with the right of the author of the XWiki.ClassSheet document. **Steps to Reproduce:** 1. Edit your user profile with the object editor and add an object of type `DocumentSheetBinding` with value `Default Class Sheet` 1. Edit your user profile with the wiki editor and add the syntax `{{async}}{{groovy}}println("Hello " + "from groovy!"){{/groovy}}{{/async}}` 1. Click "Save & View" **Expected result:** An error is displayed as the user doesn't have the right to execute the Groovy macro. **Actual result:** The text "Hello from groovy!" is displayed at the top of the document. ### Patches This has been patched in XWiki 15.0-rc-1 and 14.10.4. ### Workarounds There are no known workarounds for it. ### References https://jira.xwiki.org/browse/XWIKI-20566 https://github.com/xwiki/xwiki-platform/commit/de72760d4a3e1e9be64a10660a0c19e9534e2ec4 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki.org](https://jira.xwiki.org/) * Email us at [Security Mailing List](mailto:[email protected])
