A carefully crafted request on AJAXPreview.jsp could trigger an XSS
vulnerability on Apache JSPWiki, which could allow the attacker to execute
javascript in the victim’s browser and get some sensitive information about
the victim. 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.
