CVE-2025-6213: CWE-94 Improper Control of Generation of Code ('Code Injection') in psauxit Nginx Cache Purge Preload
The Nginx Cache Purge Preload plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.1.1 via the 'nppp_preload_cache_on_update' function. This is due to insufficient sanitization of the $_SERVER['HTTP_REFERERER'] parameter passed from the 'nppp_handle_fastcgi_cache_actions_admin_bar' function. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute code on the server.
AI Analysis
Technical Summary
The Nginx Cache Purge Preload WordPress plugin (psauxit) suffers from a remote code execution vulnerability (CWE-94) in versions up to 2.1.1. This occurs because the plugin fails to properly sanitize the $_SERVER['HTTP_REFERERER'] parameter, which is processed by the 'nppp_handle_fastcgi_cache_actions_admin_bar' function and passed to 'nppp_preload_cache_on_update'. An attacker with Administrator privileges can exploit this flaw to execute arbitrary code on the server, potentially compromising confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an authenticated administrator-level user to execute arbitrary code on the server hosting the WordPress plugin. This can lead to full system compromise, including unauthorized data access, modification, or service disruption. The CVSS v3.1 base score is 7.2, reflecting high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Administrator-level access to trusted users only and monitor for suspicious activity related to the plugin. Avoid using the vulnerable versions of the plugin if possible.
