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
Cross-Site Request Forgery (CSRF) vulnerability in Fugu Maintenance Switch plugin <= 1.5.2 versions.

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

Cross-Site Request Forgery (CSRF) vulnerability in the Fugu Maintenance Switch WordPress plugin versions 1.5.2 and below allows attackers to trick authenticated administrators into performing unintended actions (such as toggling maintenance mode) by诱骗用户执行非预期操作.

MitigationUpdate the Fugu Maintenance Switch plugin to the latest version. If no update is available, implement anti-CSRF tokens (nonce validation) on all state-changing forms and AJAX actions within the plugin.

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. Confirm plugin installation
    Navigate to WordPress Admin > Plugins or run 'wp plugin list' via WP-CLI to verify the Fugu Maintenance Switch plugin is present
    Affected if Plugin is installed and active in WordPress
  2. Check installed version
    View the plugin version in the main plugin file header (fugu-maintenance-switch.php) or run: wp plugin get fugu-maintenance-switch --format=table
    Affected if Version displayed is 1.5.2 or lower
  3. Inspect for CSRF protection in admin actions
    Examine the plugin PHP code for state-changing functions (particularly maintenance mode toggle). Verify that wp_verify_nonce() or check_admin_referer() is called before processing any admin form submissions or AJAX requests
    Affected if The plugin performs admin actions (like toggling maintenance mode) without validating nonces

The environment is affected if the Fugu Maintenance Switch plugin version is 1.5.2 or lower AND the code lacks proper nonce validation on forms that change state.
