+    {
+        "require": {
+            "enshrined/svg-sanitize": "^0.16",
+        }
+    }
+    ```
+   Also `svg` image support has been removed. If you want to use `svg` images in your project, add `image/svg+xml` to the list of allowed mime types in `CoreBundle` configuration.

+    ```yaml
+    sylius_core:
+        allowed_image_mime_types: ['image/jpeg', 'image/png', 'image/gif', 'image/webp', 'image/svg+xml']
