Security readout for executives and security teams
Plain-English summary
NEX-Forms for WordPress had missing permission checks in several AJAX functions. A logged-in low-privilege user could change or disclose plugin-related data, including form records, files, test emails, and settings. This is not shown as actively exploited in the provided sources.
Executive priority
Treat as a targeted cleanup and upgrade item, not an emergency internet-wide crisis. Prioritize sites with public registration, many low-privilege users, or sensitive form submissions.
Technical view
CVE-2020-36670 is a CWE-862 missing authorization issue affecting NEX-Forms up to and including 7.7.1. Authenticated users with subscriber permissions or higher could invoke vulnerable AJAX actions. CVSS 3.1 is 6.3 with low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is most likely on WordPress sites running NEX-Forms version 7.7.1 or earlier, especially where untrusted or stale subscriber-level accounts exist. Anonymous exploitation is not indicated by the provided sources.
Exploitation context
The bundle does not cite KEV listing or active exploitation. The attack requires authentication but only low privileges, making it relevant for membership sites, customer portals, or any WordPress deployment with many user accounts.
Researcher notes
Evidence supports missing capability checks across multiple AJAX actions with authenticated low-privilege access. The provided affected data is sparse, so avoid expanding scope beyond NEX-Forms through 7.7.1 without vendor confirmation.
Mitigation direction
- Inventory WordPress sites using NEX-Forms and identify versions up to 7.7.1.
- Upgrade NEX-Forms beyond 7.7.1 following vendor or WordPress plugin guidance.
- Remove stale WordPress accounts and restrict unnecessary subscriber-level access.
- Review plugin settings, submissions, files, and email activity for unauthorized changes.
Validation and detection
- Confirm installed NEX-Forms versions across WordPress environments.
- Check whether any subscriber-level users exist that should not have access.
- Review web and WordPress logs for unusual authenticated AJAX activity.
- Verify plugin configuration and form records match expected business state.

Missing Authorization
Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
