{"id":"CVE-2021-32732","details":"### Impact It's possible to know if a user has or not an account in a wiki related to an email address, and which username(s) is actually tied to that email by forging a request to the Forgot username page. 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)","aliases":["GHSA-vh5c-jqfg-mhrh"],"modified":"2026-02-24T01:22:19.846933Z","published":"2022-02-04T23:15:11.547Z","related":["GHSA-vh5c-jqfg-mhrh"],"references":[{"type":"ADVISORY","url":"https://github.com/xwiki/xwiki-platform/commit/69548c0320cbd772540cf4668743e69f879812cf"},{"type":"ADVISORY","url":"https://github.com/xwiki/xwiki-platform/commit/f0440dfcbba705e03f7565cd88893dde57ca3fa8"},{"type":"ADVISORY","url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-vh5c-jqfg-mhrh"},{"type":"ADVISORY","url":"https://jira.xwiki.org/browse/XWIKI-18384"},{"type":"ADVISORY","url":"https://jira.xwiki.org/browse/XWIKI-18408"},{"type":"FIX","url":"https://github.com/xwiki/xwiki-platform/commit/69548c0320cbd772540cf4668743e69f879812cf"},{"type":"FIX","url":"https://github.com/xwiki/xwiki-platform/commit/f0440dfcbba705e03f7565cd88893dde57ca3fa8"},{"type":"FIX","url":"https://jira.xwiki.org/browse/XWIKI-18384"},{"type":"FIX","url":"https://jira.xwiki.org/browse/XWIKI-18408"},{"type":"EVIDENCE","url":"https://jira.xwiki.org/browse/XWIKI-18384"},{"type":"EVIDENCE","url":"https://jira.xwiki.org/browse/XWIKI-18408"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/xwiki/xwiki-platform","events":[{"introduced":"0"},{"fixed":"648a3522f7213ef0973ffc1ecc19f3237ace437e"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2021-32732.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"}]}
