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 confidenceThis is a Missing Authorization vulnerability in the QuickCab WordPress plugin (versions through 1.3.3). The plugin fails to properly verify user permissions before allowing access to certain functionality, potentially allowing unauthenticated or lower-privileged users to perform actions they should not have access to.

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.
-
Identify if QuickCab plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'QuickCab' in the list. Alternatively, check the /wp-content/plugins/ directory for a folder named 'quickcab' or similar.Affected if QuickCab plugin is present in the WordPress installation
-
Determine the installed QuickCab versionIn Plugins > Installed Plugins, find QuickCab and note the version number displayed. Compare it to the affected range: all versions through 1.3.3Affected if The installed version is 1.3.3 or any earlier version
-
Verify if the plugin is activeCheck the Plugins screen in WordPress admin to confirm QuickCab shows as 'Active'Affected if The plugin is active and running an affected version
-
Inspect plugin PHP files for authorization checksUsing a file manager or code editor, examine the main plugin PHP files (typically quickcab.php or similar in the plugin folder) and look for AJAX action handlers (wp_ajax_ hooks) and admin page callbacks. Check if they include current_user_can() calls or capability checks before executing sensitive operations.Affected if AJAX handlers or admin functions lack current_user_can() verification or proper capability checks
-
Test for unauthenticated access to plugin functionalityIf you have access to the site externally, attempt to access known plugin endpoints or AJAX actions without logging in or with a low-privilege user account to see if they execute without requiring authentication or proper permissions.Affected if Plugin functions respond to requests from unauthenticated or low-privileged users without proper authorization
A WordPress site is affected if it has QuickCab plugin installed and active at version 1.3.3 or earlier, with AJAX handlers or admin functions that lack proper capability verification via current_user_can() checks.

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 capability checks and permission validation on all sensitive functions, AJAX actions, and admin pages within the plugin. Use WordPress nonces and current_user_can() checks to verify authorization before executing privileged operations.
