A carefully crafted editing request could trigger an XSS vulnerability
on Apache JSPWiki when parsing errors on the markdown renderer, which
could allow the attacker to execute javascript in the victim's browser
and get some sensitive information about the victim.
This issue affects Apache JSPWiki: through 2.12.3.
Users are recommended to upgrade to version 2.12.4, which fixes the issue.
