Vendor: Daniel André Eikeland
Product web page: https://github.com/pachno/pachno
Affected version: 1.0.6

Summary: Pachno is an open-source collaboration platform (formerly known as The Bug Genie)
designed for team project management, issue tracking, and documentation. It offers a module-based,
customizable environment for software development and team workflows, distributed under the
Mozilla Public License.

Desc: Input passed to the POST parameters value, comment_body, article_content, description
and message via multiple controllers is not properly sanitised before being stored in the
database and returned to the user. The application explicitly bypasses its own htmlspecialchars()
sanitiser by calling Request::getRawParameter() or Request::getParameter($name, null, false).
This can be exploited to execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

Tested on: GNU/Linux
           Apache2
           PHP/7.4
           MySQL/5.7 (MariaDB)
