The plugin fails to properly validate user permissions before allowing access to certain functionalities or data, potentially enabling unauthorized users to perform actions or access information 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.
-
Verify plugin installationNavigate to WordPress admin > Plugins and confirm 'Event Tickets Manager for WooCommerce' by WP Swings is installed and active. Note the installed version number.Affected if The plugin is installed and active, regardless of version, as the vulnerability stems from missing authorization checks in the code itself.
-
Locate plugin AJAX handlersAccess the plugin files via FTP or file manager (wp-content/plugins/event-tickets-manager-for-woocommerce/). Search for add_action('wp_ajax_*) calls in the main plugin PHP file to identify exposed AJAX endpoints.Affected if The plugin exposes AJAX endpoints without proper capability checks (current_user_can, wp_verify_nonce).
-
Inspect admin action handlersSearch for add_action('admin_action_*') or add_action('admin_post_*') calls in the plugin files. These handlers often perform sensitive operations.Affected if Admin action handlers exist without current_user_can() validation before executing sensitive operations.
-
Check for capability validationExamine the main plugin PHP file for functions that perform sensitive operations (e.g., creating/updating tickets, managing event data). Look for presence of current_user_can() or similar capability checks.Affected if Sensitive functions lack capability checks, allowing any authenticated user (including subscribers) to execute privileged actions.
You are affected if the Event Tickets Manager for WooCommerce plugin is active and its code lacks proper capability and nonce verification on AJAX endpoints and admin action handlers.

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 authorization validation on all sensitive functions and AJAX endpoints within the plugin. Ensure all admin actions verify user permissions and include nonce verification.
