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.
AnalysisAI
Remote code execution in the WPCode WordPress plugin (versions through 2.3.5) lets authenticated author-level users run arbitrary PHP on the server. Because the plugin registers its 'wpcode' custom post type without a dedicated capability_type, WordPress falls back to standard post capabilities, so any author can create and publish PHP snippet posts via the XML-RPC wp.newPost method, which are later passed to eval() when rendered through the [wpcode] shortcode. …

RemediationAI
WITHIN 24 HOURS: Identify all WordPress installations running WPCode version 2.3.5 or earlier; review XML-RPC access logs for suspicious post creation activity from author-level accounts. WITHIN 7 DAYS: Disable or restrict XML-RPC access to administrator roles only; audit all existing WPCode custom posts for malicious PHP snippets; evaluate alternative snippet management plugins if functionality is non-critical. …
