How to Fix CVE-2022-39387
To remediate this vulnerability, upgrade all affected Oidc authenticator 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.contrib.oidc</groupId>
<artifactId>oidc-authenticator</artifactId>
<version>1.29.1</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.contrib.oidcHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2022-39387, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:tree -Dincludes=org.xwiki.contrib.oidcAnalyze the terminal output to locate any version of Oidc authenticator in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.29.1), your application is affected.
Note: The mvn dependency:tree -Dincludes=org.xwiki.contrib.oidc 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.

One can then bypass the XWiki authentication altogether by specifying its own provider through the oidc.endpoint.* request parameters (or by using an XWiki-based OpenID provider with oidc.xwikiprovider.\n\nWith the same approach, one could also provide a specific group mapping through oidc.groups.mapping that would make his user automatically part of the XWikiAdminGroup\n\n### Patches\n\nPatched in version 1.29.1.\n\n### Workarounds\n\nThere is no workaround, an upgrade of the authenticator is required.\n\n### References\n\nhttps://jira.xwiki.org/browse/OIDC-118\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* Open an issue in Jira XWiki\n* Email us at our security mailing list\n\n",
