Input validation vulnerability in brodos.net Onlineshop Plugin 2.0.2

The brodos.net Onlineshop Plugin for WordPress has a security issue that allows hackers to inject harmful code into web pages. This vulnerability affects all versions of the plugin up to 2.0.2, and is caused by the plugin not properly filtering and protecting user inputs. This means that attackers with contributor-level access or higher can insert malicious code into pages, which will then be executed whenever a user opens the page.
