The module doesn't sufficiently sanitize certain attributes, which can lead to a cross-site scripting (XSS) vulnerability. This vulnerability is mitigated by the fact that an attacker must have a role with permission to enter HTML tags containing specific data attributes or the administer menu permission. Solution: Install the latest version: * If you use version 4 of the Gin theme, upgrade to Gin 4.1.4 [3]. * If you use version 5 of the Gin theme, upgrade to Gin 5.0.16 [4].
