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.","status":"published","published":"2026-06-05T09:33:46Z","modified":"2026-06-05T09:33:53Z","cvss":[{"version":"3.1","score":10,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","level":"critical"}],"cwes":["CWE-1284"],"updated_at":"2026-11-02T15:08:34.365209Z"}],"nvd":[{"id":"CVE-2026-49777","description":"Improper Validation of Specified Quantity in Input vulnerability in ShapedPlugin, LLC Product Slider Pro for WooCommerce allows Malicious Software Implanted.\n\nThis issue affects Product Slider Pro for WooCommerce: from n/a before 3.5.4.","status":"published","published":"2026-06-05T09:16:26.22Z","modified":"2026-07-23T07:10:00.113Z","cvss":[{"version":"3.1","score":10,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","level":"critical","assessor":"secondary"}],"cwes":["CWE-1284"],"updated_at":"2026-11-02T14:12:22.371367Z"}]}}
