Server-Side Request Forgery in the Everest Forms WordPress plugin (all versions up to and including 3.4.4) enables unauthenticated remote attackers to force the WordPress server to issue arbitrary outbound HTTP HEAD requests to attacker-controlled URLs. The flaw resides in the plugin's upload field handling: when a form submission triggers re-rendering due to a missing required field, unsanitized POST-supplied URLs are passed directly to WordPress's `wp_remote_head()` without any domain restriction. No active exploitation has been confirmed by CISA KEV, though the zero-authentication requirement and WordPress's broad deployment footprint elevate practical risk for internal network reconnaissance and cloud metadata endpoint probing.
Authorization bypass in the Everest Forms WordPress plugin (all versions ≤ 3.5.2) allows authenticated attackers holding any delegated Everest Forms capability to activate arbitrary already-installed WordPress plugins - including previously deactivated or known-vulnerable ones - without the WordPress core `activate_plugins` capability. The flaw exists in AJAX handlers (`class-evf-ajax.php`) and REST API endpoints (`class-evf-modules.php`) that issue nonces to any delegated EVF user on admin pages but fail to enforce the required core capability before executing plugin activation. No public exploit is identified at time of analysis, though Wordfence has published direct source code references to the vulnerable handlers, reducing the research burden for potential exploitation.
