Summary

CVE-2026-32475 is an Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) affecting the Elementor Pro plugin for WordPress. The flaw allows a remote attacker to upload malicious files to a vulnerable site, which can lead to remote code execution. It carries a Critical CVSS v3.1 base score of 9.0.

Technical details

  • Root cause: Elementor Pro fails to sufficiently restrict the type of files that can be uploaded through one of its upload-handling mechanisms.
  • Trigger conditions: The vulnerability can be exploited without prior authentication and without any user interaction, though the attack complexity is rated high.
  • Attack vector: Network — exploitable remotely over HTTP(S) against any internet-exposed WordPress site running the vulnerable plugin version.
  • Impact: Successful exploitation can compromise confidentiality, integrity, and availability of the affected system, and an uploaded malicious file (e.g., a web shell) can lead to full remote code execution on the underlying server.

Affected software

  • Elementor Pro (WordPress plugin): all versions up to and including 4.2.1.
  • Fixed in Elementor Pro version 4.2.2.

Severity

  • CVSS v3.1 Base Score: 9.0 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade Elementor Pro to version 4.2.2 or later.
  • If immediate patching is not possible: Restrict or monitor access to file upload endpoints exposed by the plugin, ensure a web application firewall is in place to inspect upload requests, and review the site’s file system and uploads directory for unexpected or executable files (e.g., PHP scripts) as a compromise indicator.
  • Ongoing: Keep WordPress core, themes, and all plugins (including the free Elementor plugin, a prerequisite for Elementor Pro) up to date, and monitor for unusual outbound activity or new admin accounts following any suspected exploitation attempt.

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.
