Attackers are actively exploiting two critical unauthenticated arbitrary file-upload vulnerabilities—CVE-2026-32475 in Elementor Pro and CVE-2026-14894 in Super Forms—to upload PHP web shells or backdoors for remote code execution and possible site takeover.…

Wordfence, Defiant, SOCRadar, and SecurityWeek report active in-the-wild exploitation of critical unauthenticated arbitrary file-upload vulnerabilities in two WordPress plugins. In Elementor Pro, CVE-2026-32475 affects form submission handling and the Forms module, is present in all versions through 4.2.1, and was fixed in version 4.2.2 on August 19, 2026; exploitation reportedly began the same day. Successful Elementor Pro exploitation requires a published page with a Form widget containing a File Upload field and writes PHP files to /wp-content/uploads/elementor/forms/, enabling remote code execution and full site compromise. In Super Forms, CVE-2026-14894 involves missing file type validation, has a reported CVSS of 9.8, was disclosed on July 9, 2026, fixed in version 6.3.314, and exploitation began on July 14, 2026. Wordfence reported more than 440,000 total blocked exploit attempts: over 250,000 against Super Forms and over 190,000 against Elementor Pro, with Super Forms exploitation peaking above 40,000 requests on August 18. SecurityWeek separately reports that Defiant blocked more than 190,000 Elementor Pro exploit attempts since the patch shipped. Observed attacks used Base64-encoded PHP web shells or backdoors, including Mushr00w_upl.php, to execute code, create administrator accounts, exfiltrate data, or seize sites. Sources disagree on some details: Elementor Pro's install base is reported as more than 6 million active installations by Wordfence but 10 million installations by SecurityWeek, and the Elementor Pro CVSS score is listed as 9.0/9.8 by The Hacker News but 9.8 by SecurityWeek.

  • Elementor Pro: CVE-2026-32475 is a critical unauthenticated arbitrary file-upload flaw in form submission handling/the Forms module; it affects all versions up to 4.2.1 and is fixed in 4.2.2.
  • Elementor Pro was publicly disclosed/patched on August 19, 2026, and attacks reportedly began on August 19, immediately after the patch shipped.
  • Successful Elementor Pro exploitation requires a published page with a Form widget containing a File Upload field.
  • Elementor Pro attacks can write PHP files to /wp-content/uploads/elementor/forms/, leading to remote code execution and full site compromise.
  • Super Forms: CVE-2026-14894 is a critical unauthenticated arbitrary file-upload flaw caused by missing file type validation, with a reported CVSS of 9.8 and a fix in version 6.3.314.
  • Super Forms was disclosed on July 9, 2026; exploitation began on July 14, 2026 and peaked above 40,000 requests on August 18, per The Hacker News.
  • Super Forms has roughly 13,000 active installations, according to Wordfence.
  • Wordfence reported more than 440,000 blocked exploit attempts across both plugins: over 250,000 for Super Forms and over 190,000 for Elementor Pro.

CVE-2026-14894
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 because the super_create_nonce nopriv AJAX action allows any unauthenticated visitor to mint a valid sf_nonce and session cookie in a single prior request, reducing exploitation to two unauthenticated HTTP requests.

CVE-2026-32475
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.

Do: Update Elementor Pro to the latest patched release (any version after 4.2.1 — the data does not name a fixed build, so apply the newest available update). Until then, use WAF rules to block unauthenticated upload attempts to Elementor endpoints, restrict or disable modules that accept file uploads from unauthenticated users, and hunt for unexpected .php files under wp-content/uploads plus new admin users or modified content as signs of compromise. The high attack complexity (AC:H) means not every install may be exploitable, but patching should be treated as urgent given the reported mass exploitation.
