How to Fix CVE-2021-32732
To remediate this vulnerability, upgrade all affected Xwiki platform administration ui dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
<dependency>
<groupId>org.xwiki.platform</groupId>
<artifactId>xwiki-platform-administration-ui</artifactId>
<version>12.10.5</version>
</dependency><dependency>
<groupId>org.xwiki.platform</groupId>
<artifactId>xwiki-platform-administration-ui</artifactId>
<version>13.2RC1</version>
</dependency>Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:tree -Dincludes=org.xwiki.platformHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2021-32732, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.xwiki.platformAnalyze the terminal output to locate any version of Xwiki platform administration ui in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 12.10.5), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.xwiki.platform command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Xwiki platform administration ui, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"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",
