Frequently Asked Questions

About CVE-2026-18351

What is CVE-2026-18351 and why is it critical?

CVE-2026-18351 is a critical unrestricted file upload vulnerability in the "Drag and Drop File Upload for Elementor Forms" WordPress plugin (developed by addonsorg), affecting all versions up to and including 1.6.0. The flaw allows unauthenticated attackers to upload arbitrary files, including executable PHP files, which can lead to full remote code execution on the affected web server. The vulnerability carries a CVSS v3.1 base score of 9.8 (Critical). Note: This vulnerability requires immediate mitigation due to its ease of exploitation and potential for complete compromise of affected systems. Source: NVD

Which versions of the Drag and Drop File Upload for Elementor Forms plugin are affected by CVE-2026-18351?

All versions up to and including 1.6.0 of the Drag and Drop File Upload for Elementor Forms WordPress plugin are affected by CVE-2026-18351. Note: Users should upgrade to a version released after 1.6.0 as soon as it becomes available. Source: CVE Program

What actions should organizations take to mitigate CVE-2026-18351?

Organizations should immediately upgrade the Drag and Drop File Upload for Elementor Forms plugin to a version released after 1.6.0 that corrects the file type validation logic. If no patch is available, disable or remove the plugin. As a network-level mitigation, block or restrict access to the plugin’s file upload handler, enforce strict file-type/extension checks at the web server or WAF layer, and configure upload directories to deny script execution (e.g., disable PHP execution in upload folders). Note: Disabling the plugin may impact form upload functionality until a secure version is available. Source: Wordfence

New CVE Detected

CVE-2026-18351 – Unauthenticated Arbitrary File Upload / RCE – Drag and Drop File Upload for Element

Be the first to know when new zero-days emerge:

Summary

CVE-2026-18351 is a critical unrestricted file upload vulnerability in the "Drag and Drop File Upload for Elementor Forms" WordPress plugin (developed by addonsorg), affecting all versions up to and including 1.6.0. The flaw allows unauthenticated attackers to upload arbitrary files, including executable PHP files, which can lead to full remote code execution on the affected web server. The vulnerability carries a CVSS v3.1 base score of 9.8 (Critical).

Technical details

  • Root cause: The plugin’s is_file_type_valid() function performs insufficient validation of uploaded file types. The attacker-controlled type parameter is used as regex keys against the MIME/extension allowlist inside the elementor_file_upload function.
  • Trigger conditions: An attacker can craft a file extension/type value that bypasses the allowlist check via regex manipulation; the filename is subsequently normalized by sanitize_file_name() in a way that can resolve to a PHP-executable extension.
  • Attack vector: Network-based, requiring no authentication and no user interaction — the plugin’s file upload endpoint used by Elementor forms is exposed to any site visitor.
  • Impact: Successful exploitation allows uploading and executing arbitrary code (e.g., a PHP web shell) on the hosting server, resulting in complete compromise of confidentiality, integrity, and availability of the affected WordPress installation.

Affected software

  • Drag and Drop File Upload for Elementor Forms (WordPress plugin) — all versions up to and including 1.6.0

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade the "Drag and Drop File Upload for Elementor Forms" plugin to a version released after 1.6.0 that corrects the file type validation logic in is_file_type_valid().
  • If no patch is available: Disable or remove the plugin until a fixed version is released. As a network-level mitigation, block or restrict access to the plugin’s file upload handler, enforce strict file-type/extension checks at the web server or WAF layer, and configure upload directories to deny script execution (e.g., disable PHP execution via server configuration in upload folders).

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
