Over 440,000 Exploit Attempts Target Super Forms and Elementor Pro RCE Flaws

Wordfence blocked 440,000+ exploit attempts against critical unauthenticated RCE flaws in WordPress plugins Super Forms and Elementor Pro.

Wordfence reports mass exploitation of two unauthenticated arbitrary file upload RCE flaws: CVE-2026-14894 in Super Forms (CVSS 9.8, fixed in 6.3.314) and CVE-2026-32475 in Elementor Pro (CVSS 9.0/9.8, fixed in 4.2.2), with over 250,000 and 190,000 blocked exploit attempts respectively. Attackers upload Base64-encoded PHP web shells such as Mushr00w_upl.php to execute code, create administrator accounts, exfiltrate data, or seize sites. Super Forms exploitation began July 14, 2026 and peaked above 40,000 requests on August 18; Elementor Pro attacks started August 19. Successful Elementor Pro exploitation requires a published page with a Form widget containing a File Upload field.

CVE-2026-148949.85%
The Super Forms – Drag & Drop Form Builder plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 6.3.313 via the sub
The Super Forms – Drag & Drop Form Builder plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 6.3.313 via the submit_form function. This is due to missing file type validation and the absence of any capability check on the submit_form nopriv AJAX handler, whose only barrier is a session nonce freely obtainable by unauthenticated visitors via a separate nopriv endpoint. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. The nonce requirement is trivially bypassed…

CVE-2026-324759.02%
Unauthenticated PHP File Upload (RCE) in Elementor Pro WordPress Plugin
Elementor Pro, the paid add-on to the widely used Elementor page builder for WordPress, is affected by an unrestricted upload of files with dangerous types (CWE-434) that can be triggered by unauthenticated attackers. An attacker sends a crafted upload request to the plugin's vulnerable endpoint and can upload a dangerous file — notably a PHP file — which the web server then executes, yielding remote code execution on the hosting account. The critical 9.0 CVSS score with scope change (S:C) and high impact across confidentiality, integrity and availability reflects that code execution lets an attacker take over the site, plant backdoors, modify content and potentially affect the underlying host. All Elementor Pro releases up to and including 4.2.1 are affected, meaning every site that has not yet updated to a fixed version is in scope. The flaw is not yet listed in CISA KEV and no public proof-of-concept is cataloged, and EPSS assigns a 2.4% 30-day exploitation probability (83rd percentile), but news reports already document hundreds of thousands of exploit attempts against Elementor Pro and Super Forms RCE flaws, so it should be treated as exploited in the wild.
