The Apache Software Foundation
Apache JSPWiki up to 2.11.2
This vulnerability leverages CVE-2021-40369, where the Denounce plugin dangerously renders user-supplied URLs. Upon re-testing CVE-2021-40369, it appears that the patch was incomplete as it was still possible to insert malicious input via the Denounce plugin.
Apache JSPWiki users should upgrade to 2.11.3 or later.
