This issue affects Product Slider Pro for WooCommerce: from n/a before 3.5.3.
No patched version is available - the vendor has applied a fix to an existing release without publishing a new version. While the patch provided by the vendor is valid, releasing it under the existing version number leaves users unable to reliably determine whether they are running a patched or vulnerable installation. As a result, we treat this as an unpatched version.
