Sprout · Sprout Forms · CVE-2020-11056
**Name of the Vulnerable Software and Affected Versions**
Sprout Forms versions prior to 3.9.0
**Description**
A potential Server-Side Template Injection issue exists in Sprout Forms, which could lead to the execution of Twig code when using custom fields in Notification Emails.
**Recommendations**
For versions prior to 3.9.0, update to version 3.9.0 to fix the issue.
As a temporary workaround for users unable to upgrade, update any Notification Emails to use the "Basic Notification (Sprout Email)" template and avoid using the "Basic Notification (Sprout Forms)" template or any custom templates that display Form Fields.
