Missing Authorization vulnerability in Blocksera Cryptocurrency Widgets Pack cryptocurrency-widgets-pack allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Cryptocurrency Widgets Pack: from n/a through <= 2.0.1.

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 · moderate confidence

Missing authorization vulnerability in the Blocksera Cryptocurrency Widgets Pack WordPress plugin allows attackers to exploit incorrectly configured access control security levels. The vulnerability appears to be an Insecure Direct Object Reference (IDOR) or broken access control issue where the plugin fails to properly validate user permissions before allowing access to certain functionalities or data.

MitigationImplement proper authorization checks across all sensitive functions and verify user privileges before executing actions. Ensure all AJAX endpoints and admin actions require proper capability verification.

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 plugin installation and version
    In WordPress admin dashboard, go to Plugins > Installed Plugins and locate 'Blocksera Cryptocurrency Widgets Pack'. Note the installed version number. If using filesystem access, check the plugin main file header in wp-content/plugins/blocksera-cryptocurrency-widgets-pack/ for the Version field.
    Affected if The plugin is installed and its version falls within any affected version range (compare your installed version to the affected ranges if publicly disclosed).
  2. Inspect AJAX endpoint access controls
    Examine the plugin PHP files for AJAX action handlers (search for 'add_action' with 'wp_ajax_' or 'wp_ajax_nopriv_' hooks). Review each handler to verify it calls current_user_can() or proper capability checks before executing sensitive operations.
    Affected if AJAX endpoints exist that lack capability verification (current_user_can() checks) before processing requests.
  3. Review admin action authorization
    Scan plugin files for admin action hooks (add_action calls handling admin.php requests). Check if these hooks verify user capabilities using functions like current_user_can(), admin_url() validation, or nonce verification before performing privileged operations.
    Affected if Admin actions lack proper authorization checks and can be triggered by lower-privileged users.
  4. Check for IDOR vulnerabilities in object references
    Analyze plugin code for database queries or data access that relies on user-supplied identifiers (GET/POST parameters) without validating ownership or user permissions. Look for patterns where IDs from requests are used directly in queries without ownership verification.
    Affected if Plugin accepts user IDs or object IDs from requests and returns data without verifying the requesting user has rights to access that specific data.

Your environment is affected if the Blocksera Cryptocurrency Widgets Pack plugin is installed and its AJAX endpoints or admin actions lack proper capability verification, allowing unauthorized access to sensitive functionality.
