The Meeting Room Booking System (MRBS) is a PHP-based application for booking meeting rooms. Prior to version 1.12.2, a user-supplied private/local URI can be made to be fetched without checks. Version 1.12.2 contains a fix. No known workarounds are available.

MRBS (Meeting Room Booking System) before 1.12.3 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject script via the error parameter of viewentry.php. Attackers can send crafted links to logged-in users to read CSRF tokens, modify or delete bookings, or perform administrative actions.
