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 Essential Chat Support plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.0.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to reset all plugin configuration settings — including general settings, display rules, custom CSS, and WooCommerce tab settings — to their defaults by sending a POST request with ecs_reset_settings=1.

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 · high confidence

The Essential Chat Support WordPress plugin lacks proper authorization checks on a settings reset function. An unauthenticated attacker can send a POST request with the parameter ecs_reset_settings=1 to reset all plugin configuration (general settings, display rules, custom CSS, WooCommerce tab settings) to defaults without any authentication.

MitigationUntil a patched version is released, consider disabling the plugin or implementing web server-level access controls to block unauthorized POST requests containing ecs_reset_settings. Users should monitor for unexpected configuration changes.

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 Essential Chat Support plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and search for 'Essential Chat Support', or check the /wp-content/plugins/ directory for an 'essential-chat-support' folder.
    Affected if The plugin is installed and active on the WordPress site.
  2. Identify installed plugin version
    In WordPress admin plugins list, click on the plugin name to view details and version number, or inspect the main plugin PHP file header for the 'Version' tag.
    Affected if The installed version falls within the affected range (check against the vendor's advisory once published).
  3. Inspect the reset settings function accessibility
    Locate the PHP file containing the settings reset function (typically in the plugin's main file or settings class) and examine the function for missing capability checks or nonce verification before executing the reset.
    Affected if The function lacks checks for user authentication (like current_user_can) or valid nonce verification before processing the reset.
  4. Monitor for unauthorized reset attempts
    Review web server access logs and WordPress debug logs for POST requests containing the parameter 'ecs_reset_settings=1' from unauthorized IP addresses.
    Affected if Any unauthenticated POST requests with ecs_reset_settings=1 are present in the logs.
  5. Verify current plugin configuration state
    Navigate to the plugin settings page in WordPress admin (Essential Chat Support > Settings) and check if all settings have been reset to default values unexpectedly.
    Affected if Plugin settings (general settings, display rules, custom CSS, WooCommerce tab settings) have been reverted to defaults without intentional admin action.

The environment is affected if the Essential Chat Support WordPress plugin is installed, the installed version is within the affected range, and the settings reset function lacks proper authorization checks, allowing unauthenticated users to reset configuration.
