Original source description

Impact

Users with access to a form's settings can include malicious Twig code into fields that support Twig. These might be the Submission Title or the Success Message. This code will then be executed upon creating a submission, or rendering the text.

This is listed as low-medium severity due to requiring control panel access to edit a form's settings.

Patches

This has been fixed in Formie 2.1.6. Users should ensure they are running at least this version.
