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 aBlocks – WordPress Gutenberg Blocks plugin for WordPress is vulnerable to unauthorized modification of data and disclosure of sensitive information due to missing capability checks on multiple AJAX actions in all versions up to, and including, 2.4.0. This makes it possible for authenticated attackers, with subscriber level access and above, to read plugin settings including block visibility, maintenance mode configuration, and third-party email marketing API keys, as well as read sensitive configuration data including API keys for email marketing services.

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 aBlocks WordPress plugin versions up to 2.4.0 contain multiple AJAX actions that lack proper capability checks, allowing any authenticated user with subscriber-level access to invoke these endpoints. This enables unauthorized access to sensitive plugin settings including block visibility configurations, maintenance mode settings, and third-party email marketing service API keys.

MitigationUpdate the plugin to version 2.4.1 or later which includes proper capability checks on all AJAX actions. Alternatively, manually add current_user_can() checks to all AJAX handlers in 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. Verify aBlocks plugin is installed
    Check for the presence of the aBlocks plugin in your WordPress installation under wp-content/plugins/ablocks/ or search for 'aBlocks' in the WordPress admin Plugins page
    Affected if The plugin is installed and active in WordPress
  2. Determine installed plugin version
    Open the main plugin file (typically ablocks.php) and locate the 'Version' header in the plugin comment block, or check the version displayed in the WordPress admin Plugins list for aBlocks
    Affected if The installed version is 2.4.0 or lower (any version up to and including 2.4.0)
  3. Check AJAX action accessibility
    Examine the plugin's PHP files for AJAX handlers (wp_ajax_ and wp_ajax_nopriv_ hooks) and verify whether current_user_can() capability checks are present at the start of these handler functions
    Affected if AJAX handlers exist that do NOT include current_user_can() checks or use capability checks that allow subscriber-level users (such as 'read' capability only)
  4. Identify exposed sensitive settings
    Search plugin code for endpoints that handle block visibility configurations, maintenance mode settings, or third-party API key storage (look for references to functions handling these features and their associated AJAX actions)
    Affected if The plugin processes requests for these settings without verifying user capabilities

You are affected if the aBlocks plugin is installed with version 2.4.0 or lower and contains AJAX actions accessible to authenticated users with subscriber-level access without proper capability verification.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update the plugin to version 2.4.1 or later which includes proper capability checks on all AJAX actions. Alternatively, manually add current_user_can() checks to all AJAX handlers in the plugin.

Recommended fix High confidence

aBlocks plugin version 2.4.1 or later (any version higher than 2.4.0)

  1. Log in to the WordPress admin dashboard
  2. Navigate to Plugins > Installed Plugins
  3. Locate the 'aBlocks – WordPress Gutenberg Blocks' plugin
  4. If an update is available, click 'Update Now' to install the latest version that addresses the missing authorization vulnerability
  5. After updating, verify that subscriber-level users can no longer access AJAX actions that expose sensitive settings or API keys
