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.
