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)"}],"metrics":[{"cvssV3_1":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":7.5,"baseSeverity":"HIGH","confidentialityImpact":"HIGH","integrityImpact":"NONE","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"}}],"problemTypes":[{"descriptions":[{"cweId":"CWE-352","description":"CWE-352: Cross-Site Request Forgery (CSRF)","lang":"en","type":"CWE"}]}],"providerMetadata":{"dateUpdated":"2022-02-04T22:15:13.000Z","orgId":"a0819718-46f1-4df5-94e2-005712e83aaa","shortName":"GitHub_M"},"references":[{"tags":["x_refsource_CONFIRM"],"url":"https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-vh5c-jqfg-mhrh"},{"tags":["x_refsource_MISC"],"url":"https://github.com/xwiki/xwiki-platform/commit/69548c0320cbd772540cf4668743e69f879812cf"},{"tags":["x_refsource_MISC"],"url":"https://github.com/xwiki/xwiki-platform/commit/f0440dfcbba705e03f7565cd88893dde57ca3fa8"},{"tags":["x_refsource_MISC"],"url":"https://jira.xwiki.org/browse/XWIKI-18384"},{"tags":["x_refsource_MISC"],"url":"https://jira.xwiki.org/browse/XWIKI-18408"}],"source":{"advisory":"GHSA-vh5c-jqfg-mhrh","discovery":"UNKNOWN"},"title":"Cross-Site Request Forgery in xwiki-platform","x_legacyV4Record":{"CVE_data_meta":{"ASSIGNER":"security-advisories@github.com","ID":"CVE-2021-32732","STATE":"PUBLIC","TITLE":"Cross-Site Request Forgery in xwiki-platform"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"xwiki-platform","version":{"version_data":[{"version_value":"< 12.10.5 "},{"version_value":">= 13.0, < 13.2RC1"}]}}]},"vendor_name":"xwiki"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","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.
