verbb/formie Server-Side Template Injection for variable-enabled settings
ImpactUsers 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.PatchesThis has been fixed in Formie 2.1.6. Users should ensure they are running at least this version.
