Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The Under Construction / Maintenance Mode from Acurax plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.6 via the REST API. This makes it possible for unauthenticated attackers to obtain the contents of posts and pages when maintenance mode is active thus bypassing the protection provided by the plugin.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The Acurax Under Construction / Maintenance Mode plugin for WordPress has a vulnerability in all versions up to 2.6 where the REST API endpoints remain publicly accessible even when maintenance mode is active. This allows unauthenticated attackers to bypass the maintenance mode protection and retrieve the full contents of posts and pages via REST API calls, exposing sensitive information that should be hidden.

MitigationUpdate the Acurax plugin to a version beyond 2.6 which should contain the fix for properly restricting REST API access during maintenance mode. If no patched version is available, consider alternative maintenance mode solutions or manually restrict REST API endpoints via server configuration.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Acurax plugin is installed
    Check WordPress plugins directory or admin panel for 'Acurax Under Construction / Maintenance Mode' plugin
    Affected if Plugin is not installed on the WordPress site
  2. Determine installed plugin version
    In WordPress admin, go to Plugins > Installed Plugins and locate the Acurax plugin to view its version number, or check the plugin's main PHP file for the Version header comment
    Affected if Version is 2.6 or lower
  3. Confirm maintenance mode is enabled
    Access the plugin settings in WordPress admin under the Acurax plugin menu and verify if 'Enable Maintenance Mode' or similar option is turned on
    Affected if Maintenance mode is currently active on the site
  4. Test REST API accessibility during maintenance mode
    With the site showing maintenance mode, attempt a REST API request such as GET /wp-json/wp/v2/posts or GET /wp-json/wp/v2/pages using a tool like curl or browser developer tools while NOT logged in
    Affected if REST API returns full post/page content (200 OK with data) instead of being blocked or returning maintenance page

A site is affected if it has Acurax Under Construction / Maintenance Mode plugin version 2.6 or lower with maintenance mode enabled, and the REST API remains accessible to unauthenticated users exposing content that should be hidden.

Upgrade available Upgrade to a release after 2.6
Interim mitigation

Update the Acurax plugin to a version beyond 2.6 which should contain the fix for properly restricting REST API access during maintenance mode. If no patched version is available, consider alternative maintenance mode solutions or manually restrict REST API endpoints via server configuration.

Recommended fix Moderate confidence

latest available version on wordpress.org (after 2.6)
