CyberRota Analysis
AI-GeneratedThe WP Grid Builder plugin for WordPress is susceptible to privilege escalation due to inadequate authorization and meta key validation in the `update()` handler of the `/wp-json/wpgb/v2/metadata` REST endpoint. This vulnerability allows authenticated users with Subscriber-level access or higher to escalate their privileges to Administrator by manipulating their `wp_capabilities` user meta. WordPress site administrators using this plugin should prioritize patching to mitigate the risk of unauthorized access and potential exploitation.
Original NVD Description
The WP Grid Builder plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 2.3.3. This is due to missing authorization and meta key validation in the `update()` handler for the `/wp-json/wpgb/v2/metadata` REST endpoint. This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to Administrator by updating their own `wp_capabilities` user meta with a crafted nested array payload.
