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 GenerateBlocks plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'get_option_rest' function in all versions up to, and including, 2.1.1. This makes it possible for authenticated attackers, with contributor level access and above, to read arbitrary WordPress options, including sensitive information such as SMTP credentials, API keys, and other data stored by other plugins.

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 GenerateBlocks WordPress plugin has a broken access control vulnerability in its REST API endpoint 'get_option_rest'. This endpoint lacks proper capability checks, allowing any authenticated user with contributor-level permissions to read arbitrary WordPress options stored in the database, including sensitive credentials like SMTP settings and API keys from other plugins.

MitigationUpdate GenerateBlocks to version 2.1.2 or later which includes proper capability validation on the REST endpoint. If immediate update is not possible, audit user accounts with contributor-level access and implement monitoring for unusual options API access patterns.

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 GenerateBlocks plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for GenerateBlocks, or check the file /wp-content/plugins/generateblocks/ for the plugin directory
    Affected if GenerateBlocks plugin is installed and active
  2. Check installed GenerateBlocks version
    In WordPress admin Plugins list, click on GenerateBlocks to view version details, or read the version in /wp-content/plugins/generateblocks/readme.txt or the plugin main PHP file header
    Affected if Version is below 2.1.2 (or version cannot be determined and plugin is present)
  3. Verify REST API endpoint accessibility
    Send an authenticated REST API request to /wp-json/generateblocks/v1/get_option_rest?option_name=siteurl using a contributor-level user account (use wp-rest-api or curl with nonces)
    Affected if Endpoint returns the option value without proper authorization check (returns data for any authenticated contributor+ user)
  4. Audit contributor-level user accounts
    In WordPress admin, go to Users > All Users and filter or check for users with Contributor role. Review if these accounts are expected to have access
    Affected if There are contributor-level accounts present and the plugin version is below 2.1.2

User is affected if GenerateBlocks plugin is installed with version below 2.1.2 and the REST endpoint responds to contributor-level authenticated requests without proper capability validation.

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

Update GenerateBlocks to version 2.1.2 or later which includes proper capability validation on the REST endpoint. If immediate update is not possible, audit user accounts with contributor-level access and implement monitoring for unusual options API access patterns.

Recommended fix Moderate confidence

GenerateBlocks version 2.1.2 or later

  1. 1. Log in to the WordPress admin dashboard
  2. 2. Navigate to Plugins > Installed Plugins
  3. 3. Locate GenerateBlocks in the plugin list
  4. 4. If an update is available, click 'Update Now' to update GenerateBlocks to the latest version
  5. 5. Alternatively, download the latest version of GenerateBlocks from the WordPress plugin repository and upload it manually
  6. 6. After updating, verify the plugin is running on a version higher than 2.1.1
