## Affected

- LimeSurvey: 7.4.0

## Description

An authenticated LimeSurvey Community Edition 7.4.0 user with the global Surveys: create permission can store a JavaScript-breaking value in the date_min attribute of a Date/Time question. When another user renders the affected question, LimeSurvey inserts the stored value into a single-quoted inline JavaScript literal without JavaScript-context encoding.
