AnalysisAI

Remote code execution in the ACPT (Pro) - Custom Post Types Plugin for WordPress (versions through 2.0.47) allows unauthenticated remote attackers to inject and execute arbitrary code on the underlying WordPress host. The CVSS 3.1 base score of 10.0 with a scope change (S:C) indicates the flaw escapes the plugin sandbox and compromises the entire WordPress installation. No public exploit has been identified at time of analysis, but the trivial attack profile (network, no auth, no UI) makes this a high-priority patching target.

Technical ContextAI

ACPT (Pro) is a commercial WordPress plugin that lets site administrators define and manage custom post types, taxonomies, and meta fields. The root cause is CWE-94 (Improper Control of Generation of Code, 'Code Injection'), meaning attacker-supplied input is incorporated into a code path that is later evaluated or included by PHP - classic vectors include eval(), include/require with attacker-controlled paths, or unsafe template rendering. The CPE cpe:2.3:a:acpt:acpt_(pro)_-_custom_post_types_plugin_for_wordpress:*:*:* confirms all versions of the Pro edition are in scope. Because WordPress plugins execute within the main wp-includes/PHP runtime, successful code injection yields full webserver-level execution rather than isolated plugin behavior.

RemediationAI

Upstream fix availability is not independently confirmed in the supplied data - the Patchstack advisory documents the vulnerability through 2.0.47 but no fixed version is named, so administrators should consult the Patchstack entry (https://patchstack.com/database/wordpress/plugin/advanced-custom-post-type/vulnerability/wordpress-acpt-pro-custom-post-types-plugin-for-wordpress-plugin-2-0-47-remote-code-execution-rce-vulnerability) and the ACPT vendor portal for a release newer than 2.0.47 and upgrade immediately once available. Until a patched version is installed, deactivate and remove the ACPT Pro plugin from production sites, since a CVSS 10.0 unauthenticated RCE in an active plugin cannot be safely left running. If removal is operationally impossible, place the WordPress site behind a WAF (Patchstack, Wordfence, or Cloudflare managed rules) with virtual-patching enabled for this CVE, restrict access to /wp-admin and to any ACPT REST/AJAX endpoints by source IP, and monitor PHP error logs and web-access logs for anomalous POSTs targeting ACPT routes - note that WAF rules are a stopgap and may be bypassed by novel payload encodings.
