CVE-2026-3596: CWE-862 Missing Authorization in imprintnext Riaxe Product Customizer
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.
AI Analysis
Technical Summary
CVE-2026-3596 affects the Riaxe Product Customizer plugin for WordPress, where an unauthenticated AJAX action ('wp_ajax_nopriv_install-imprint') allows attackers to call the ink_pd_add_option() function. This function updates WordPress options based on attacker-controlled POST parameters without nonce verification, capability checks, or option name restrictions. Consequently, attackers can modify arbitrary options, including enabling user registration and setting the default user role to administrator, leading to privilege escalation. The vulnerability is present in all versions up to 2.1.2. The CVSS 3.1 base score is 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows unauthenticated attackers to escalate privileges by modifying WordPress options arbitrarily. This can lead to unauthorized administrative access by enabling user registration and assigning the administrator role to new users. The impact includes full compromise of the affected WordPress site’s confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the affected plugin or disable it to prevent exploitation. Monitor for updates from the vendor or trusted security sources regarding patches or mitigations.
