Description :Improper Validation of Specified Quantity in Input vulnerability in ShapedPlugin, LLC Product Slider Pro for WooCommerce allows Malicious Software Implanted.

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.

Severity: 10.0 | CRITICAL
