Block Class enables you to add custom attributes to blocks. The module did not sufficiently sanitize custom attribute input, allowing for potential XSS attacks when malicious JavaScript was injected as a custom attribute. This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer block classes".
