New CVE Detected

CVE-2026-10818 – Unauthenticated Arbitrary File Upload leading to RCE – WPForms Pro ≤ 1.10.1.1

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

Summary

CVE-2026-10818 is a high-severity arbitrary file upload vulnerability (CWE-434) in WPForms Pro, a WordPress form-builder plugin active on over 6 million websites. The flaw affects all versions up to and including 1.10.1.1 and allows unauthenticated remote attackers to upload executable files to the server, leading to Remote Code Execution (RCE). The CVE carries a CVSS v3.1 score of 8.1 (HIGH).

Technical details

  • Root cause: The ajax_chunk_upload_finalize function performs file type validation only after chunk metadata and the assembled file contents have already been written to disk. When validation subsequently fails, the assembled file is not deleted, leaving the malicious file persisted on the server’s filesystem.
  • Trigger conditions: The attack targets WordPress sites running WPForms Pro with file upload fields active in published forms. The CVSS Attack Complexity is rated High (AC:H), which reflects the specific conditions required (e.g., presence of a file upload field on an exposed form).
  • Attack vector: Fully network-accessible (AV:N), requiring no authentication (PR:N) and no user interaction (UI:N). An attacker sends crafted chunked upload requests to the AJAX endpoint directly, with no prior login needed.
  • Impact: Successful exploitation results in an attacker-controlled executable file residing on the web server. If the web server processes or executes the file (e.g., via a web shell), the attacker achieves Remote Code Execution, leading to full compromise of confidentiality, integrity, and availability of the affected system.

Affected software

  • WPForms Pro – all versions up to and including 1.10.1.1

Severity

  • CVSS v3.1 Base Score: 8.1 (HIGH)
  • Vector String: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
  • CWE: CWE-434 – Unrestricted Upload of File with Dangerous Type

Mitigation and recommended actions

  • Immediate: Update WPForms Pro to the latest available version beyond 1.10.1.1. Monitor the official WPForms changelog for a security release addressing this CVE.
  • Interim workaround: If immediate patching is not possible, disable or remove any file upload fields from publicly accessible WPForms forms to eliminate the exposed attack surface.
  • Network mitigation: Restrict access to the WPForms AJAX upload endpoint (wp-admin/admin-ajax.php with WPForms upload actions) via WAF rules or network controls where operationally feasible.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

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.
