XWiki Platform vulnerable to privilege escalation via properties with wiki syntax that are executed with wrong author

### Impact It's possible to use the right of an existing document content author to execute a text area property. To reproduce: * As an admin with programming rights, create a new user without script or programming right. * Login with the freshly created user. * Insert the following text in source mode in the about section: ``` {{groovy}}println("hello from groovy!"){{/groovy}} ``` * Click "Save & View" ### Patches This has been patched in XWiki 14.10, 14.4.7, and 13.10.11. ### Workarounds No known workaround. ### References https://jira.xwiki.org/browse/XWIKI-20373 ### 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:security@xwiki.org)
