Vulnerability Description

The Elementor Website Builder plugin for WordPress is vulnerable to unauthorized execution of several AJAX actions due to a missing capability check in the ~/core/app/modules/onboarding/module.php file that make it possible for attackers to modify site data in addition to uploading malicious files that can be used to obtain remote code execution, in versions 3.6.0 to 3.6.2.

  1. Maintain the observed Atomicorp detections. Keep your Atomicorp commercial rules current and confirm that the selected observed rules (377360 ) have not been locally disabled. Atomicorp commercial rules are enabled by default. If you use Atomic WAF, review the applicable policy and rule settings. These observations are detection-only; review the resulting events and do not assume they block exploitation.

  2. Apply the vendor’s remediation. WAF protection is defense in depth and does not replace upgrading or following the affected vendor’s guidance.

    • Affected versions: elemntor Elementor Website Builder version 3.6.0.
    • Affected versions: elemntor Elementor Website Builder version 3.6.1.
    • Affected versions: elemntor Elementor Website Builder version 3.6.2.
    • The CVE record does not include written upgrade or workaround instructions, but it does publish the following patch or mitigation reference:

  3. Validate after changes. Confirm rule updates are current, review WAF events for the affected application, and test application behavior after vendor upgrades, mitigations, or local policy changes.

Research Notes

Atomicorp WAF protections are designed around attack techniques and exploit behaviors, allowing existing protections to apply across multiple vulnerabilities without requiring a unique rule for every CVE.

Research Note Context

This research note documents exploit-technique analysis associated with this vulnerability and references Atomicorp WAF protections observed during engineering review, testing, or validation activities.

Atomicorp security controls are generally designed to identify and mitigate attack techniques and exploit behaviors rather than individual CVE identifiers. As a result, protections developed for one vulnerability may also apply to related attack variants and future vulnerabilities using similar techniques.
