{"cve":"CVE-2026-3596","nvd":{"published":"2026-04-16T06:16:15.667","modified":"2026-06-17T10:43:50.627","status":"Deferred","description":"The Riaxe Product Customizer plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.1.2. The plugin registers an unauthenticated AJAX action ('wp_ajax_nopriv_install-imprint') that maps to the ink_pd_add_option() function. This function reads 'option' and 'opt_value' from $_POST, then calls delete_option() followed by add_option() using these attacker-controlled values without any nonce verification, capability checks, or option name allowlist. This makes it possible for unauthenticated attackers to update arbitrary WordPress options, which can be leveraged for privilege escalation by enabling user registration and setting the default user role to administrator.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/riaxe-product-customizer/tags/2.1.2/riaxe-product-designer.php#L183","https://plugins.trac.wordpress.org/browser/riaxe-product-customizer/tags/2.1.2/riaxe-product-designer.php#L5045","https://plugins.trac.wordpress.org/browser/riaxe-product-customizer/tags/2.1.2/riaxe-product-designer.php#L5046","https://plugins.trac.wordpress.org/browser/riaxe-product-customizer/tags/2.1.2/riaxe-product-designer.php#L5047","https://plugins.trac.wordpress.org/browser/riaxe-product-customizer/tags/2.1.2/riaxe-product-designer.php#L5058"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-3596","score":0.00789,"percentile":0.56235,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
