Description

Craft is a platform for creating digital experiences. In Craft versions 4.0.0-RC1 through 4.16.17 and 5.0.0-RC1 through 5.8.21, a stored XSS vulnerability exists in the Number field type settings. The Prefix and Suffix fields are rendered using the |md|raw Twig filter without proper escaping, allowing script execution when the Number field is displayed on users' profiles. This issue is patched in versions 4.16.18 and 5.8.22.
