What is CVE-2026-46382?

A security issue exists in the Meeting Room Booking System (MRBS), a widely used PHP application for booking meeting rooms.

This oversight exposes the application to potential misuse and data leaks. Users are highly encouraged to update to version 1.12.2, which includes a fix addressing this vulnerability. Unfortunately, no known workarounds are available to mitigate this issue, making immediate action necessary for those using affected versions.
