FKIE_CVE-2025-6213

Vulnerability from fkie_nvd - Published: 2025-07-22 10:15 - Updated: 2025-08-01 19:15
Severity ?
7.2 (High) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Summary
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.
