{"id":"GHSA-vh5c-jqfg-mhrh","summary":"Cross-Site Request Forgery in xwiki-platform","details":"### Impact\nIt'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 tight 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.\n\n### Patches\nThis issue has been patched in XWiki 12.10.5 and 13.2RC1. Two different patches are provided:\n  - a first one to fix the CSRF problem\n  - a more complex one that now relies on sending an email for the Forgot username process.\n\n### Workarounds\nIt'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\n\nIn 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.\n\n### References\n  * https://jira.xwiki.org/browse/XWIKI-18384\n  * https://jira.xwiki.org/browse/XWIKI-18408\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [Jira XWiki](https://jira.xwiki.org)\n* Email us at [security ML](mailto:security@xwiki.org)\n","aliases":["CVE-2021-32732"],"modified":"2026-01-30T02:31:26.772560Z","published":"2022-02-10T22:42:46Z","related":["CVE-2021-32732"],"database_specific":{"github_reviewed_at":"2022-02-07T16:35:35Z","nvd_published_at":"2022-02-04T23:15:00Z","cwe_ids":["CWE-352"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-vh5c-jqfg-mhrh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-32732"},{"type":"WEB","url":"https://github.com/xwiki/xwiki-platform/commit/69548c0320cbd772540cf4668743e69f879812cf"},{"type":"WEB","url":"https://github.com/xwiki/xwiki-platform/commit/f0440dfcbba705e03f7565cd88893dde57ca3fa8"},{"type":"WEB","url":"https://github.com/xwiki/xwiki-platform"},{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-18384"},{"type":"WEB","url":"https://jira.xwiki.org/browse/XWIKI-18408"}],"affected":[{"package":{"name":"org.xwiki.platform:xwiki-platform-administration-ui","ecosystem":"Maven","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-administration-ui"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"12.10.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/02/GHSA-vh5c-jqfg-mhrh/GHSA-vh5c-jqfg-mhrh.json"}},{"package":{"name":"org.xwiki.platform:xwiki-platform-administration-ui","ecosystem":"Maven","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-administration-ui"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"13.0"},{"fixed":"13.2RC1"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 13.1","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/02/GHSA-vh5c-jqfg-mhrh/GHSA-vh5c-jqfg-mhrh.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
