CVE-2024-21648
XWiki has no right protection on rollback action
Description
### Impact The rollback action is missing a right protection: it means that a user can rollback to a previous version of the page to gain rights they don't have anymore. This vulnerability impacts all version of XWiki since rollback action is available. ### Patches The problem has been patched in XWiki 14.10.16, 15.5.3 and 15.8-rc-1 by ensuring that the rights are checked before performing the rollback. ### Workarounds There's no workaround for this vulnerability, except paying attention to delete old versions of documents that could allow users to gain more rights. ### References * JIRA ticket: https://jira.xwiki.org/browse/XWIKI-21257 * Commit: [4de72875ca49602796165412741033bfdbf1e680](https://github.com/xwiki/xwiki-platform/commit/4de72875ca49602796165412741033bfdbf1e680) ### 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:security@xwiki.org)
