A carefully crafted plugin link invocation could trigger an XSS
vulnerability on Apache JSPWiki, related to the Denounce plugin, which
could allow the attacker to execute javascript in the victim’s browser and
get some sensitive information about the victim. Apache JSPWiki users
should upgrade to 2.11.0 or later.
