CVE-2020-36730: CMP <= 3.8.1 - Missing Authorization

The CMP for WordPress is vulnerable to authorization bypass due to a missing capability check on the cmp_get_post_detail(), niteo_export_csv(), and cmp_disable_comingsoon_ajax() functions in versions up to, and including, 3.8.1. This makes it possible for unauthenticated attackers to read posts, export subscriber lists, and/or deactivate the plugin.

Security readout for executives and security teams

Plain-English summary

A WordPress maintenance-page plugin could let unauthenticated outsiders read posts, export subscriber lists, or turn off the plugin. The main business concern is data exposure and unexpected site state changes on affected WordPress sites running CMP versions up to 3.8.1.

Executive priority

Prioritize remediation on public WordPress sites because the vulnerability needs no login and can expose subscriber data or alter site availability controls. Treat it as high urgency where CMP is installed.

Technical view

CMP for WordPress up to and including 3.8.1 lacks authorization checks in cmp_get_post_detail(), niteo_export_csv(), and cmp_disable_comingsoon_ajax(). The issue is CWE-862 with CVSS 3.1 score 8.3, network reachable, low complexity, no privileges, and no user interaction required.

Likely exposure

Exposure is most likely on public WordPress sites using CMP – Coming Soon & Maintenance Plugin by NiteoThemes at versions up to 3.8.1, especially sites collecting subscriber lists through the plugin.

Exploitation context

The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Public advisories document the affected plugin, vulnerable functions, and unauthenticated impact, which is enough to treat internet-facing installs as urgent.

Researcher notes

Evidence supports missing authorization, not authentication bypass across WordPress generally. Avoid assuming broader WordPress compromise. The affected callable functions and impacts are identified, but the provided bundle does not establish active exploitation or a specific fixed version number.

Mitigation direction

  • Inventory WordPress sites for CMP Coming Soon & Maintenance Plugin by NiteoThemes.
  • Upgrade CMP beyond 3.8.1, confirming the fixed release in vendor guidance.
  • Remove or disable the plugin where no longer required.
  • Review possible subscriber-list exposure and unexpected plugin deactivation events.
  • Monitor WordPress activity for anomalous unauthenticated requests targeting plugin functionality.

Validation and detection

  • Check installed CMP plugin versions across all WordPress properties.
  • Confirm no production site remains on CMP version 3.8.1 or earlier.
  • Review web and WordPress logs for suspicious access around CMP endpoints.
  • Verify subscriber export access requires proper authorization after remediation.
  • Document affected sites, remediation dates, and any suspected data exposure.

Missing Authorization

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