CVE-2026-8832

May 27, 2026, 2:50 p.m.

8.8
High

Description

The WPCode - Insert Headers and Footers + Custom Code Snippets - WordPress Code Manager plugin for WordPress is vulnerable to Remote Code Execution in versions up to, and including, 2.3.5 This is due to the 'wpcode' custom post type being registered without a custom capability_type or capability restrictions in the wpcode_register_post_type() function, allowing WordPress core to fall back to standard post capabilities for all creation paths including XML-RPC. This makes it possible for authenticated attackers, with author-level access and above, to create and publish executable PHP snippet posts via XML-RPC wp.newPost, which are then executed server-side via eval() in the run_eval() function when the snippet is rendered through the [wpcode] shortcode.
