{"id":"CVE-2021-32732","state":"PUBLISHED","title":"Cross-Site Request Forgery in xwiki-platform","description":"### 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)","publishedAt":"2022-02-04T22:15:13.000Z","updatedAt":"2025-04-22T18:27:32.831Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["xwiki xwiki-platform"],"affected":[{"vendor":"xwiki","product":"xwiki-platform","versions":[{"version":"< 12.10.5 ","status":"affected"},{"version":">= 13.0, < 13.2RC1","status":"affected"}]}],"references":["https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-vh5c-jqfg-mhrh","https://github.com/xwiki/xwiki-platform/commit/69548c0320cbd772540cf4668743e69f879812cf","https://github.com/xwiki/xwiki-platform/commit/f0440dfcbba705e03f7565cd88893dde57ca3fa8","https://jira.xwiki.org/browse/XWIKI-18384","https://jira.xwiki.org/browse/XWIKI-18408"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T19:48:33.225Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2021/32xxx/CVE-2021-32732.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2021-32732","state":"PUBLISHED","datePublished":"2022-02-04T22:15:13.000Z","dateUpdated":"2025-04-22T18:27:32.831Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2021-05-12T00:00:00.000Z"},"containers":{"cna":{"title":"Cross-Site Request Forgery in xwiki-platform","descriptions":[{"lang":"en","value":"### 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.
