GHSA-R843-RVX7-3RJG

Vulnerability from github – Published: 2026-06-05 09:33 – Updated: 2026-06-05 09:33

Details

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)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
