CVE-2026-11818 arraytics CVE debrief

Who should care

Users of WPCafe – Restaurant Menu, Online Food Ordering & Table Booking System plugin for WordPress, especially those with subscriber-level access and above, should be aware of this vulnerability and take necessary actions to protect their sites. This includes updating to a patched version, restricting access to sensitive workflows, and monitoring for suspicious activity.

Technical summary

The WPCafe plugin does not properly verify user authorization, allowing authenticated attackers with subscriber-level access to manage notification flow workflows intended for administrators. The vulnerability exists in all versions up to and including 3.0.14 and is due to insufficient checks, with only a wp_rest nonce check in place, which can be obtained by any logged-in user. This could lead to unauthorized actions being performed, including listing, creating, updating, deleting, cloning, and bulk-deleting notification flow workflows.

Defensive priority

Medium priority due to the potential for authenticated attackers to perform unauthorized actions.

Recommended defensive actions

• Update to a patched version of the WPCafe plugin
• Restrict access to sensitive workflows and endpoints
• Monitor for suspicious activity related to notification flow workflows
• Implement additional authorization checks for user actions
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
