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 多说社会化评论框 plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.2. The vulnerability exists due to a missing capability and nonce check on a directly web-accessible API endpoint, combined with a trivially forgeable HMAC-SHA1 signature keyed on an always-empty WordPress option, which allows the endpoint's `update_option` handler to pass attacker-controlled `option` and `value` parameters directly to WordPress's `update_option` function without any allowlist or sanitization. This makes it possible for unauthenticated attackers to update arbitrary WordPress options — such as setting `default_role` to `administrator` and enabling open registration — and subsequently register an account with full administrator privileges.

dbcve analysis · high confidence

The Duoshuo WordPress plugin (versions up to 1.2) has a privilege escalation vulnerability in its web-accessible API endpoint. The endpoint lacks capability and nonce verification, relying on a trivially forgeable HMAC-SHA1 signature based on an always-empty WordPress option. This allows unauthenticated attackers to manipulate arbitrary WordPress options via the `update_option` function, enabling them to set `default_role` to administrator and enable open registration, then register an admin account.

MitigationReplace the weak HMAC-SHA1 implementation with proper nonce validation and capability checks (e.g., `manage_options`), implement an allowlist of permitted options, and restrict the endpoint to authenticated users with appropriate privileges.

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 Duoshuo plugin is installed
    Check the WordPress plugins directory for the duoshuo folder and inspect its main PHP file for the version number, typically found in the plugin header comment
    Affected if The plugin is installed and the version is 1.2 or lower
  2. Verify the vulnerable API endpoint exists
    Check for the presence of the Duoshuo API endpoint file (commonly duoshuo.php or similar in the plugin directory) that handles the signature verification
    Affected if The API endpoint file exists and is web-accessible
  3. Locate the HMAC-SHA1 signature verification code
    Search the Duoshuo plugin PHP files for functions performing HMAC-SHA1 signature checks, particularly those using a WordPress option (get_option) as the HMAC secret key
    Affected if The code uses HMAC-SHA1 with a key derived from a WordPress option that is empty or easily guessable
  4. Confirm update_option is called without capability checks
    Inspect the API handler code for calls to update_option() or related functions that modify WordPress options, and verify they lack current_user_can() or check_admin_referer() validation
    Affected if update_option is invoked without proper capability or nonce verification
  5. Check current WordPress registration settings
    Review the WordPress site options (via wp_options table or WordPress admin) for default_role and users_can_register settings
    Affected if users_can_register is enabled and default_role is set to administrator, indicating possible exploitation

You are affected if the Duoshuo plugin version 1.2 or lower is installed with its web-accessible API endpoint using HMAC-SHA1 verification based on an empty option key and lacking capability checks before update_option calls.

Mitigation

Replace the weak HMAC-SHA1 implementation with proper nonce validation and capability checks (e.g., `manage_options`), implement an allowlist of permitted options, and restrict the endpoint to authenticated users with appropriate privileges.
