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.

Missing Authorization vulnerability in syedamirhussain91 DB Backup db-backup allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects DB Backup: from n/a through <= 6.0.

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

A missing authorization vulnerability in the DB Backup WordPress plugin allows unauthenticated or unauthorized users to access backup functionality due to incorrectly configured access control security levels. The plugin fails to properly validate user permissions before allowing access to sensitive backup operations, enabling attackers to potentially obtain database backups without proper authentication.

MitigationImplement proper authorization checks at all plugin endpoints and functions that handle backup operations, ensuring role-based access control (RBAC) is enforced and unauthenticated users cannot access or trigger backup functionality.

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 DB Backup plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'DB Backup' or 'WP Database Backup'. Note the installed version number displayed.
    Affected if The DB Backup plugin is installed and the version falls within any affected version range (compare your version to the plugin's release history).
  2. Identify backup-related endpoints
    Check the plugin directory (wp-content/plugins/db-backup or similar) for PHP files that handle backup operations. Look for functions that generate or serve backup files, typically containing keywords like 'backup', 'download', 'export', or 'dump'.
    Affected if The plugin exposes backup-related endpoints (URLs) that can be accessed without authentication.
  3. Test unauthenticated access to backup functionality
    Using a browser or curl tool, attempt to access known backup URLs (such as those ending in ?action=backup, ?page=db-backup, or direct paths to backup handlers) without logging into WordPress. Observe if a backup file is generated or served without requiring login.
    Affected if Backup functionality returns a valid response or downloads a backup file without requiring authentication (HTTP 200 without login redirect).
  4. Verify authorization checks in plugin code
    Examine the main plugin PHP file(s) for functions handling backup requests. Look for current_user_can(), wp_verify_nonce(), or other WordPress capability checks before executing backup operations. Search for 'add_action' or 'add_hook' entries related to backup functions.
    Affected if No capability checks (like current_user_can) or nonce verification appear before backup operations, or such checks are missing entirely.
  5. Check WordPress user role configuration
    In WordPress admin, go to Users > User Role Editor (or similar) and verify if any custom roles have been granted backup-related capabilities. Also check if the plugin has modified default role permissions.
    Affected if Subscriber, Contributor, or unauthenticated (logged-out) users have backup-related capabilities assigned, or the plugin has granted excessive permissions.

Your environment is affected if the DB Backup plugin is installed and backup endpoints respond without requiring authentication or proper capability checks.
