Note that since this page does not have a CSRF check it's quite easy to perform a lot of those requests. ### Patches This issue has been patched in XWiki 12.10.5 and 13.2RC1. Two different patches are provided: - a first one to fix the CSRF problem - a more complex one that now relies on sending an email for the Forgot username process. ### Workarounds It's possible to fix the problem without uprading by editing the ForgotUsername page in version below 13.x, to use the following code: https://github.com/xwiki/xwiki-platform/blob/69548c0320cbd772540cf4668743e69f879812cf/xwiki-platform-core/xwiki-platform-administration/xwiki-platform-administration-ui/src/main/resources/XWiki/ForgotUsername.xml#L39-L123 In version after 13.x it's also possible to edit manually the forgotusername.vm file, but it's really encouraged to upgrade the version here. ### References * https://jira.xwiki.org/browse/XWIKI-18384 * https://jira.xwiki.org/browse/XWIKI-18408 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira XWiki](https://jira.xwiki.org) * Email us at [security ML](mailto:security@xwiki.org)","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2021-32732","url":"https://www.suse.com/security/cve/CVE-2021-32732"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1190121 for CVE-2021-32732","url":"https://bugzilla.suse.com/1190121"}],"title":"SUSE CVE CVE-2021-32732","tracking":{"current_release_date":"2025-02-17T05:23:24Z","generator":{"date":"2023-02-15T03:40:54Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2021-32732","initial_release_date":"2023-02-15T03:40:54Z","revision_history":[{"date":"2023-02-15T03:40:54Z","number":"2","summary":"Current version"},{"date":"2025-01-01T04:26:10Z","number":"3","summary":"Current version"},{"date":"2025-02-15T05:00:48Z","number":"4","summary":"Current version"},{"date":"2025-02-17T05:23:24Z","number":"5","summary":"Current version"}],"status":"interim","version":"5"}}}
