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 confidenceA missing authorization vulnerability exists in the iZooto web push plugin (version <= 3.7.20) that allows attackers to exploit incorrectly configured access control security levels. The vulnerability stems from a lack of proper authentication checks on certain functionality, potentially allowing unauthorized access to administrative or sensitive operations.

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 checksWork through these to decide whether this CVE applies to you.
-
Check iZooto plugin versionNavigate to WordPress admin dashboard > Plugins > Installed Plugins > locate iZooto Web Push and view the Version field, or check the plugin header in wp-content/plugins/izooto-web-push/izooto-web-push.phpAffected if version is 3.7.20 or lower
-
Identify plugin AJAX actionsSearch plugin PHP files for 'add_action' calls with 'wp_ajax_' or 'wp_ajax_nopriv_' prefixes to find registered AJAX endpoints, or use a network scanner while interacting with the plugin frontendAffected if endpoints registered with nopriv hooks are found that handle sensitive data or actions
-
Test endpoint accessibilitySend unauthenticated HTTP requests to identified plugin endpoints (e.g., via curl or browser developer tools) to see if they return expected data or perform actions without requiring loginAffected if requests succeed without authentication where they should require it
-
Review capability checksExamine plugin source code for 'current_user_can', 'check_admin_referer', or 'verify_nonce' calls around sensitive functions; grep for these patterns in the plugin directoryAffected if no capability or nonce verification is found before sensitive operations
-
Check user role configurationIn WordPress admin > Users > Roles, verify if iZooto creates custom roles with overly permissive capabilities, or if default roles have unexpected access to plugin featuresAffected if custom roles with elevated permissions exist without proper restriction
If the iZooto plugin version is 3.7.20 or below AND unauthenticated access to plugin functions is possible without proper capability checks, the environment is affected by this missing authorization vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper role-based access control (RBAC) and authorization checks on all sensitive endpoints and administrative functions. Validate user permissions before executing any privileged operations.
