[Juan Pablo Santos Rodríguez <juanpablo () apache org>]

Severity: Medium

Affected versions:

- Apache JSPWiki  before Apache JSPWiki up to 2.12.2

Description:

A carefully crafted request when creating a header link using the
wiki markup syntax, which could allow the attacker to execute javascript
 in the victim's browser and get some sensitive information about the
