CVE-2024-10800: CWE-862 Missing Authorization in vanquish WordPress User Extra Fields
The WordPress User Extra Fields plugin for WordPress is vulnerable to privilege escalation due to a missing capability check on the ajax_save_fields() function in all versions up to, and including, 16.6. This makes it possible for authenticated attackers, with subscriber-level access and above, to add custom fields that can be updated and then use the check_and_overwrite_wp_or_woocommerce_fields function to update the wp_capabilities field to have administrator privileges.
AI Analysis
Technical Summary
The WordPress User Extra Fields plugin suffers from a missing capability check in the ajax_save_fields() function, allowing authenticated users with low privileges to escalate their rights. By manipulating custom fields and leveraging the check_and_overwrite_wp_or_woocommerce_fields function, attackers can overwrite the wp_capabilities field to gain administrator-level access. This vulnerability affects all versions up to 16.6 and is classified under CWE-862 (Missing Authorization). The CVSS 3.1 base score is 8.8, reflecting network attack vector, low attack complexity, required privileges at the low level, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an authenticated user with subscriber-level or higher privileges to escalate to administrator privileges. This compromises the entire WordPress site, enabling full control over content, user management, and potentially the underlying server environment. The impact includes complete loss of confidentiality, integrity, and availability of the affected WordPress installation.
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 trusted users only and consider disabling or removing the WordPress User Extra Fields plugin if possible. Monitor for updates from the plugin vendor or WordPress security channels to apply an official fix promptly once available.
