Critical Vulnerability in Elementor Pro Allows Unauthenticated File Upload & RCE Exploit

Post Views: 10

Critical vulnerability in Elementor Pro enables unauthorized file uploads and remote code execution

Overview of the Vulnerability

A severe security flaw in the Elementor Pro WordPress plugin, designated CVE-2026-32475, presents a significant risk by allowing attackers to execute arbitrary code on affected servers through unauthenticated file uploads. This issue impacts all versions of Elementor Pro prior to 4.2.2, as reported by Patchstack.

Technical Details

The vulnerability stems from a flaw in the File Upload module, which improperly handles empty filenames during validation and processing, according to Bleeping Computer. The flaw arises from a mismatch between two distinct processes within the module: one for validating file inputs and another for processing them.

Attackers can exploit this discrepancy by constructing a multipart request that includes an empty filename in the initial segment, followed by a malicious PHP payload. During validation, the system overlooks the empty filename, while the processing stage moves the payload to a publicly accessible directory (wp-content/uploads/elementor/forms/). Once uploaded, the attacker can determine the payload’s filename through methods such as timing analysis or automated email responses, then trigger execution by accessing the file’s URL. This enables full control over the server under the web application’s privileges.

Patch and Recommendations

The vulnerability was addressed in Elementor Pro version 4.2.2, which includes patches to align the validation and processing workflows. Administrators are strongly advised to apply the update immediately and conduct thorough scans for unauthorized files.

Importance of Timely Updates

Although no instances of active exploitation have been confirmed, systems utilizing Elementor Pro forms with file upload capabilities remain exposed. The flaw highlights the importance of timely patch management and careful configuration of third-party plugins. Organizations relying on WordPress for content management should prioritize monitoring for similar vulnerabilities in their deployed tools.

Conclusion

No evidence of widespread attacks has emerged, but the potential for severe compromise underscores the need for proactive security measures. Users are encouraged to review their plugin configurations and ensure all software is updated to the latest secure versions.
