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
Unauthenticated Insecure Direct Object References (IDOR) in Clean Login <= 1.15 versions.

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

Unauthenticated Insecure Direct Object Reference (IDOR) vulnerability in Clean Login plugin versions 1.15 and earlier allows remote attackers to access or modify objects (such as user data, sessions, or protected resources) without proper authorization by manipulating object references in HTTP requests.

MitigationUpgrade Clean Login plugin to version newer than 1.15; if no patch available, implement proper object-level authorization checks on all sensitive endpoints and validate user permissions before allowing access to any resource.

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. Identify if Clean Login plugin is installed
    Check your WordPress plugins directory or admin panel for 'Clean Login' plugin. Common paths: wp-content/plugins/clean-login/ or via WP-CLI: wp plugin list --search=clean-login
    Affected if Clean Login plugin is present in the WordPress installation
  2. Determine installed plugin version
    Check the plugin main file (usually clean-login.php) for the Version header, or inspect plugin metadata via WordPress admin > Plugins > Clean Login, or use WP-CLI: wp plugin get clean-login --format=json
    Affected if Version is 1.15 or earlier, or version cannot be determined (assume vulnerable)
  3. Verify unauthenticated endpoint exposure
    Test accessing common Clean Login endpoints without authentication: /wp-json/clean-login/v1/ or similar REST routes, login/registration forms, or user profile pages. Use curl or browser to request these endpoints without providing credentials.
    Affected if Endpoints return user data, session info, or allow modifications without requiring authentication
  4. Check for IDOR in object references
    Inspect HTTP requests to Clean Login plugin endpoints. Look for parameters that reference user IDs, session tokens, or object handles (e.g., ?user_id=1, ?session=abc). Modify these values in requests to see if unauthorized access occurs.
    Affected if Changing object references (user IDs, session IDs) in requests yields access to data or actions for other users without authorization errors

Environment is affected if Clean Login plugin version 1.15 or earlier is installed AND unauthenticated endpoints are accessible, allowing unauthorized access or modification of objects by manipulating reference values in HTTP requests.
