What immediate steps should I take to mitigate this vulnerability?

Since no fix is currently available for this vulnerability, immediate mitigation steps include:

• Restrict access to the WordPress admin area to trusted IP addresses to reduce the risk of attackers tricking logged-in admins.
• Educate administrators to avoid clicking on suspicious links or visiting untrusted websites while logged into the WordPress admin panel.
• Implement web application firewall (WAF) rules to detect and block requests attempting to delete coupons via the vulnerable URL pattern.
• Regularly back up your WordPress database and coupon data to enable recovery in case of unauthorized deletions.

Monitoring and logging suspicious activity related to coupon deletion URLs can also help in early detection and response.
