The package whoogle-search before 0.7.2 are vulnerable to Cross-site Scripting (XSS) via the query string parameter q. In the case where it does not contain the http string, it is used to build the error_message that is then rendered in the error.html template, using the [flask.render_template](https://flask.palletsprojects.com/en/2.1.x/api/flask.render_template) function. However, the error_message is rendered using the [| safe filter](https://jinja.palletsprojects.com/en/3.1.x/templates/working-with-automatic-escaping), meaning the user input is not escaped.

The default configuration of the Jinja templating engine used in the Identity Provider (IdP) server in Ipsilon 0.1.0 before 1.0.1 does not enable auto-escaping, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via template variables. NOTE: This may be a duplicate of CVE-2015-5216. Moreover, the Jinja development team does not enable auto-escape by default for performance issues as explained in https://jinja.palletsprojects.com/en/master/faq/#why-is-autoescaping-not-the-default.
